Depending on which moves David Stearns and company make this offseason, and how and where Travis Shaw fits into the equation, the middle of the infield figures to be an area of special interest. Young and intriguing players abound, with still more waiting in the wings. Highlighted below are a few of the players most likely to impact up the middle next season.

Major Leagues

Orlando Arcia, SS

Arcia arrived in 2016 shouldering high expectations. He was Milwaukee’s best prospect since Ryan Braun came along in 2007 and changed the history of the franchise. Arcia produced a very nice age-22 season in 2017, finishing with 3.4 Wins Above Replacement Player (WARP) and vaulting to the top of Milwaukee’s list of talents aged 25 and under, just ahead of Domingo Santana. Times have changed.

Arcia regressed to a .214 True Average (TAv) and 0.0 WARP in 2018, losing playing time to a handful of low-profile players and heading into the All-Star Break below the Mendoza line. After some time sorting out his swing in the minors, he roared back to life in the second half, clawing playing time back from the just-imported Jonathan Schoop and helping to lead the team through their playoff charge.

Arcia is still just 24 years old, is a ton of fun to watch on the infield, and has offered fans glimpses of his offensive potential over the last two years. He’ll be starting at shortstop next spring, perhaps with a somewhat shorter leash than he had at the start of 2018.

Travis Shaw, 2B

Shaw famously crossed over to the right side of the infield at the trade deadline, freeing up the hot corner for Mike Moustakas. He’s 6’4” and 230 pounds, but showed solid glove work and good instincts at the keystone, especially for someone learning on the fly. As lines between positions blur around the league, the big man could see more time at second base in 2019.

Shaw recorded 32 home runs in just under 500 at bats in 2018, marking his second year in a row reaching that milestone. He showed a nice approach at the plate, drawing 78 walks to offset his 108 strikeouts. He also topped the 4-WARP plateau for the second straight season, making him the kind of cheap, under-the-radar star that franchises like Milwaukee need in order to sustain success.

There may be more in the tank. Shaw is still in the midst of his physical prime, and recorded an average exit velocity in 2018 that was right in line with his career norms. Even so, his BABIP dipped 70 points from 2017. Some of this can be attributed to an uptick in fly balls. But if Shaw can add back a few points to his batting average, and perhaps decrease his reliance on pulling the ball in certain counts, 2019 could be the year that he breaks out as one of the better-rounded sluggers in the league.

Jonathan Schoop, 2B/SS

Schoop enjoyed a monster 2017 in Baltimore, accumulating 4.7 WARP and whacking 32 home runs while providing surprisingly good defense at second base. 2018 didn’t go as well, particularly after the trade that sent him to Milwaukee in exchange for Jonathan Villar (still hurts), Luis Ortiz, and Jean Carmona. That’s a bit of a haul, but Schoop was hot, and he’s been a special bat in the past. Milwaukee didn’t get that player; Schoop struggled to a .202/.246/.331 line in 46 games for the Brewers.

Schoop is controllable for 2019, though it’s less clear whether Milwaukee intends to offer him a contract. MLB Trade Rumors pegs his salary at $10.1 million in his final year of arbitration, a hefty sum for a small market team to spend on a player with plenty of question marks. Never a patient hitter, Schoop relies on the quality of his contact to generate value with the bat. Worryingly, his exit velocity, launch angle, hard hit percentage, and barrel percentage were all down in 2018, per Statcast; Schoop actually outperformed his Expected Weighted On-Base Average (xWOBA).

Losing three players for a few weeks of sub-replacement performance would hurt; so would paying $10 M for a player who could end up on the bench. 2019 will be a crucial year for Schoop, no matter whose jersey he ends up wearing.

Hernán Pérez, UTIL

Pérez, 28 next Opening Day, continued to slip a little after an exciting 2016 campaign. Even so, he provided average offense (.258 TAv) and credible defense at seven different positions. There’s value in that. Pérez didn’t manage quite as much power in 2018 as he did the previous two seasons, and his K/BB ratio is as unseemly as ever. He shouldn’t be anyone’s idea of a starting player on a playoff-caliber team at this point, but he’s a fine option to have around in case of injury or early-season ineffectiveness. Projected at a reasonable $2.7 million next year by MLB Trade Rumors, he’s a good guy to have around the back end of the roster.

Tyler Saladino, UTIL

Saladino made some noise upon his initial promotion to Milwaukee, batting .298 in the first half of the season. But he was injured in May, missed all of June, and looked fairly awful in July and September. So in the end, he wound up with a pretty Saladino-esque line of .246/.302/.398. He’s 29 years old, and is projected to make $1.0 million next year by MLB Trade Rumors. He had a nice year in 2016, running up 1.4 WARP in half a season with the White Sox. That’s looking like the peak of his big league career at this point.

Minor Leagues

Mauricio Dubon, 2B/SS

The 2018 season could have gone very differently for Mauricio Dubon. The young infielder tore through his first 27 games in Triple-A, batting .343/.348/.574 with some nice doubles power and not too many whiffs. Then he tore through his ACL, and missed the rest of the season. It was a case of bad timing for Dubon and the Brewers; Orlando Arcia and Eric Sogard were struggling with the big club, and Dubon might have been the first man up. Instead, he’ll aim to occupy that position in 2019.

Dubon makes a lot of contact, and routinely runs strikeout rates in the low-to-mid-teens. He’s quick on the base paths, though not a tremendous threat to steal. And he’s teased some intriguing power at various points in his minor league career, though it tends to come and go. Dubon is a capable defender at shortstop, though he fits better at second base long-term. One knock on his game: He doesn’t walk much. Even so, the floor here is something like Hernán Pérez, perhaps with less ability to roam the outfield grass (though it wouldn’t surprise me to see him shagging some extra fly balls in spring training). As for the ceiling? Well…

Keston Hiura, 2B

Keston Hiura is looking more and more like a blue-chip prospect at the keystone. There’s little remaining doubt about his bat, though he’s oddly susceptible to strikeouts for someone who projects as a Grade 60 or better hitter (on a scale where 50 is average). As many of you know, Hiura combined for a .293 batting average, 13 home runs, and 34 doubles in his first full minor league season, reaching Double-A along the way. Were it not for a minor thumb injury suffered in July, those numbers all may have been better; Hiura’s performance dipped considerably in late July and August. Currently, he’s smacking the ball around to the tune of a .333 average and 30 RBIs in the Arizona Fall League. It’s been said that the man can hit.

Happily, he’s answering questions about his work in the dirt, too. Through last season and into the AFL, Hiura has looked like an average defender at second, maybe a tick below. That’s a great outcome for someone who’s missed so many reps. If Hiura continues to progress at all defensively, he should be able to handle himself just fine at the keystone.

Hiura looks like a threat to hit .300 with 20-25 home runs and a mess of doubles. Even now, he could probably muster a decent-enough slash line against big league pitching. He’ll be up soon; how long the Brewers wait on a promotion may ultimately depend on how well whoever’s making the majority of big league starts is performing.

Free Agents

There are a number of interesting names on the free agent market that could help shore up Milwaukee’s infield depth. That’s particularly true if the Brewers buy into Travis Shaw at second and cast around for upgrades at third. Mike Moustakas is a natural target there, as he performed ably for the Brewers down the stretch and quietly offers average skills on both sides of the ball. He’ll likely get a multi-year deal this time out, but the commitment shouldn’t be too costly, in either dollars or years.

Jed Lowrie, Marwin Gonzalez, Josh Harrison, and Neil Walker could all help at either second or third base. Any of those names could sign for between two and four years, with Gonzalez probably representing the best and most expensive option. But even Josh Donaldson may not be out of reach, depending on how leery teams are of his age and injury history.

Should the Brewers feel that Hiura will be ready to make an impact by mid-season, they could be tempted to simply bridge the gap with a cheap one-year deal. The most logical name, in that case, may be Ian Kinsler’s (Kinsler was also mentioned as a possible target by Andrew Salzman in a piece earlier this month.) Kinsler doesn’t offer too much with the bat anymore, but he still provides solid defense. He turns 37 next year, and will likely settle for a one-year deal.

A quick recap on roster rules: the non-tender deadline this offseason is November 30. By that date, teams have to offer a contract to all players on the 40-man roster with fewer than six years of service time. If the team does not offer a contract to a player, then he becomes a free agent. Because Jonathan Schoop has 5.027 years of Major League service time and has not signed any extension, the Brewers have until November 30 to decide if they want to retain him for next season.

Jonathon Schoop is the greatest young power hitting second baseman of all time. There’s a lot to unpack there, but if we wanted to measure by players twenty-six and under who have played at least fifty percent of their games at second base, he’s hit the most home runs. However, impressive raw home run totals don’t necessarily mean a player is a star; even with that fun fact to his name, Schoop’s bat completely fell apart in 2018 after showing so much promise in 2017.

As a twenty-five year old second basemen in 2017, Schoop had a .280 True Average (TAv) and produced 37.6 Value Over Replacement Player (VORP), which estimates the number of runs Schoop produced beyond a freely available minor league replacement. PECOTA pegged him for a regression with .256 TAv and 15.8 VORP, yet his numbers sunk lower. Schoop’s plate discipline remained remarkably similar. His swing rate rose four percentage points to 56.8 percent, while his contact rate (71.4) and swinging strike rate (28.6) remained virtually unchanged from 2017, so his strikeout percentage only rose from twenty-one percent to twenty-three percent. The biggest difference is that his walk rate sunk from 5.2 percent to 3.8 percent, both of which are below average. Schoop’s walk rate would have placed him in the bottom five of all qualified hitters if he’d had enough at bats.

As I noted back in August, there was no smoking gun on Schoop’s poor performance at the plate, he just wasn’t hitting the ball as well. From that article’s publication date on August 13^th, Statcast numbers only slightly recovered. Even with some improvement his barrel percentage, exit velocity, launch angle, and hard hit percentage all were career lows. His expected WOBA placed in the bottom 1 percent of all hitters.

The Brewers traded for a player they probably saw as a buy low candidate. If they elect to offer Schoop arbitration, it likely means that they see something in his 2018 performance that they believe can be corrected to get him back to his 2017 numbers.

One projection for Schoop’s potential arbitration award places him at a $10.1M salary in 2019, which would be 3^rd on the team in salary, just above Christian Yelich, in case you needed another reminder about how great that contract is for the Brewers. The only other potential second basemen on the 40-man roster, presuming that Shaw is back at third base on Opening Day, are Tyler Saladino, Hernan Perez and Mauricio Dubon. None of these players are projected as a starting caliber player on a contending team.] in 2019.

The most intriguing internal option to replace Schoop would be Keston Hiura. Our mother site’s midseason top 50 prospects list had Hiura at number five and claimed that Hiura was “basically major-league ready” back when it was posted in mid-July. If the team agrees with the assessment, then he could be the starting at second by May 1, with service time manipulation likely preventing him from starting the season with the big-league club. While he’s considered a bat-first prospect, if the Brewers could shift and game plan their way into making Travis Shaw league average at second, fans shouldn’t be too worried about Hiura.

The Brewers could also look at potential free agents who could sign a one-year deal and provide flexibility in case the team wants to wait on Hiura (or if he proves not to be ready). Ian Kinsler had a terrible post-trade run with the Red Sox capped with baserunning and fielding blunders in Game 3 of the World Series. However, he provided above average defense according to Fielding Runs Above Average (FRAA) (even if it wasn’t quite Gold Glove worthy). If you squint, his offense wasn’t terrible in 2018! From his nadir on May 28 through his trade to Boston on July 30, he slashed .286/.349/.518, which is above his career line of .271/.339/.443. One wouldn’t expect a two-month hot streak to be his baseline production going forward, but it does show he has some life left in his bat, and could serve a useful role as a bridge to Hiura.

The Brewers are lucky to be in the position where they don’t need to double down on the Schoop trade. It would hurt the front office’s external perception to write off the acquisition as a total loss after three months of poor production, but I don’t believe that’s going to factor into their calculation. Milwaukee is always going to operate on a limited budget, but if the team decides its best choices are Schoop and Hiura, two different budget issues arise. Is the team willing to keep Schoop at more than $10 M when there’s a non-zero chance he’s not worth a roster spot? If Hiura shines in spring training and proves he’s the best player for the team, are they willing to ignore service time considerations and have him start the season with the team? If not, who would cover the gap of at least two weeks? Milwaukee’s front office has a few weeks to make these decisions, but whichever direction they turn will shed light on their internal evaluations of the players in question.

With the most frustrating stretch of the season concluded, the only point I want to dwell on from the weekend is that Sunday’s game should have been delayed before it ended. Understanding it was right before the All-Star break and everyone wanted to go home/on vacation, those were appalling conditions for baseball and it’s not a reach to believe that the final play of the game was affected by the elements. This is purely anecdotal but it certainly feels these situations have been occurring with more regularity. I don’t know if that means that some discretion in these instances should be ceded to MLB’s central office, which could be a neutral arbiter and not as willing to fret over travel schedules, but playing in a downpour entails risks to player health irrespective of game integrity issues. It’s also a problem for the people who paid to go to the game and have to make the choice between taking cover or getting soaked in their seats. Stadiums aren’t designed to provide much cover to spectators and considering that MLB is in the throes of a drop in attendance, creating these situations for fans doesn’t make for a pleasant experience which would draw one out to the park.

Ahem. Now that I’ve gotten that out of my system, I want to look at two recent additions to the twenty-five man roster who are primed to offer positive production over the second half of the season.

The pitching staff has been stretched as injuries pile up and the team has not had an off day since June 25. Milwaukee called up Corbin Burnes last week to bolster the bullpen. The Baseball Prospectus mothership ran an article on his call-up, anticipating a tightened pitch mix of a fastball and slider and the potential to pitch for more than an inning at a time. Lo and behold Burnes pitched twice this past week and went for two innings in each appearance!

While Burnes did prominently feature his fastball and slider, he did not ditch his curveball, which the Baseball Prospectus prospect team described as “average”. His velocity has ticked up in the bullpen role. Last season as a starter, he was throwing his fastball in the low 90s and the slider in the low 80s, but now he’s sitting around 96 for the fastball and his slider has jumped to 88.

Burnes has done a decent job keeping his fastball elevated and, in an admittedly small sample size, his spin rate on the pitch has been elite, which makes the pitch appear even higher than it is. Batters are swinging at a lot of his fastballs and while the whiffs aren’t there yet, most of the contact hasn’t been productive and there’s only been one single off the pitch.

The Brewers preseason prospect list noted that Burnes “trusts both his breaking balls a lot”, which is a concern when they don’t actually break. While hitters haven’t yet crushed any mistakes, his early pitch patterns do show that he has confidence he can throw the slider and curveball at any time. His highest usage rate of the breakers against left handed comes is when he’s behind in the count and he overwhelming has utilized his slider against righties when he’s ahead or there’s two strikes in the count. Thus far, those pitches haven’t been in the zone, but Burnes is getting swings and misses, so the approach has worked.

There is a prime opportunity to Burnes to stick with the big league club. While the Brewers still have a top three bullpen according to Deserved Run Average (DRA), they’ve been poor in the month of July, and a fresh arm which can pitch multiple quality innings in an appearance is a valuable commodity.

In an admittedly small sample size, Tyler Saladino has the fifth highest True Average (TAv) amongst Brewers position players in 2018. Since his activation from the disabled list on July 5^th, he’s taken over the starting shortstop role from Brad Miller, who held it temporarily after Orlando Arcia’s demotion. Below is an abbreviated PECOTA preseason projection for Saladino, which assumed a part-time role and replacement player level production.

Saladino has exceeded his 90^th percentile projection. His TAv was .295 before yesterday’s two hit game and while defensive stats are not reliable at such small sample sizes, his 1.9 FRAA compares favorably with Arcia’s 3.7 in less than half of Arcia’s games played in Milwaukee.

Patience and power have been the keys to his step forward. Saladino doubled his walk rate in 2017 to 8.2 percent, which was right around the MLB average after years of a below average rate. He’s mostly kept those gains this season as he’s walked in 6.8 percent of his at bats.

There hasn’t been a large change in Saladino’s swing rate, but where he’s back has produced the greatest results. He’s swung at about 16 percent fewer pitches out of the strike zone, which has covered up his increased whiff rate and kept his walks relatively level.

Saladino has also made a tweak in the pitches he’s swinging at. Last season he was swinging at anything that was up or away and out of the zone. This year he’s been more focused on pitches middle and in, which he can pull. The difference is even more apparent if you just look at fastballs (2017 and 2018). He’s gone to the opposite field less than ever before.

The change in approach has also been paired with an increase in launch angle. This increase actually started in 2017 as he bumped his launch angle from 7.9 to 12.9 degrees. Saladino has increased it further to 14.8 in 2018. However, in 2017 the change didn’t seem to have an effect. There was no increase in his exit velocity and his hard hit percentage and barrel percentage also fell. Saladino is currently running career high numbers in all three categories, which is fueling his improved performance at the plate.

While Saladino can’t replace the big hitters who are currently hurt, he’s providing above average production and lengthens the lineup. Whereas Arcia was an offensive blackhole and Brad Miller isn’t competent enough defensively to handle the position, Saladino, at his current level is what the team needs… unless they trade for Manny Machado.
