Checking In on Fantasy Relevant Platoon Hitters

Hitter platoons are a necessary part of baseball and have been utilized to some effect since the 1880s. Boston Braves manager George Stallings employed a successful outfield platoon in their 1914 World Series championship season. Legendary manager Casey Stengel utilized them prominently with the Braves pre-WWII and during the Yankees dynasty from 1949-1953. The term “platoon” was first used in the 1940s. Platoon usage decreased in the 80s and 90s and has since returned to prominence this century, even more so in the last several years due to heavier reliance on data.

In fantasy baseball, we can optimize our starting lineups in daily and weekly leagues by paying close attention to hitter platoon splits and baseball managers’ tendencies. Astute fantasy managers pay attention to the upcoming week’s matchups and make sure to bench a left-handed hitter who does not start against left-handed pitchers in a weekly league where that hitter’s team is facing four or five lefties. During draft season, those managers are careful not to overload their roster with too many extreme platoon bats like Kerry Carpenter so they can maximize the number of plate appearances, and by virtue of that, fantasy stats. Since we are one month into the season, I wanted to review the relevant platoon hitters. How are they performing? Who is likely to remain in their platoon? Who is in danger of falling into one? Who is working their way out of one? Let’s dig in.

Likely to Remain on the Strong Side Platoon

Lawrence Butler was a top 200 fantasy pick. Though he reached 20 HR, 20 SB in his second season, Butler hit .234 and struggled relative to his high ADP last spring. Butler has two home runs and four stolen bases in 95 plate appearances, but has mostly struggled to produce (.186/.263.279). He was in the starting lineup for one of the A’s seven games against a LHP and has fallen to hitting eighth over the last two weeks. There will come a time this season when Butler is red-hot and possibly even leading off for a stretch, but with the emergence of Carlos Cortes (LH), Tyler Soderstrom (LH) in the outfield, and two viable short-side platoon righties (Colby Thomas and Zack Gelof), the margin for error for Butler is slim.

For most of his career, Reds centerfielder TJ Friedl has shifted back and forth from strong-side platoon (vs. RHPs only) to a full-time bat. His career wRC+ splits are close (109 vs. L, 102 vs. R), though Friedl has faced RHPs 3.5x more. Friedl is locked into a platoon with righty centerfielder Dane Myers, which is an arrangement that should continue as long as both remain healthy. Friedl may be sitting on your waiver wire, but should only be considered in deeper (15-team) formats.

Kyle Manzardo and Kerry Carpenter are the two best power hitters in this group. Manzardo played a little bit against lefties last season, batting .186 against them in 95 PAs. He had a 83 wRC+ vs. lefties and a 119 vs. righties. Manzardo is in a strict platoon with Rhys Hoskins at first base. Manzardo will heat up at some point. He has only one home run this season after hitting 27 in 2025. Carpenter is a stud against RHPs (career 138 wRC+, .262 ISO) and a dud against LHPs (69, .124). The Tigers have faced mostly righty starters this season and manager A.J. Hinch is a very platoon friendly manager. Carpenter could earn some starts against lefties this season, but will likely never be a full-time starter against them.

Owen Caissie has some pop, but he is also the easiest hitter to punch out. Don’t pay much attention to his strikeout rate against lefties in a small sample (69% in 16 PA) as much his overall strikeout rate of 43.3%. Caissie is slashing .207/.256/.354 and has not been a plus defender. It’s possible that he is danger of being demoted.

Before the season started, the managers of the Phillies and Rangers told us that Brandon Marsh and Evan Carter would see more starts against lefties. Neither deserve more as both have struggled mightily against them. Marsh has earned a few starts against lefties (6 of 12), but fewer since rookie Felix Reyes was promoted. Let’s see how interim manager Don Mattingly handles it. It will probably be more of the same, though. The Phillies are slated to face mostly RHPs over the next two weeks. We can stream him while his bat remains hot, but he’s fungible in 12-team leagues. Carter’s batting average is around the Mendoza Line and he is hitless in 20 plate appearances against southpaws.

Rookie Carson Benge hasn’t started against a lefty and it will likely remain that way in the short term. Further solidifying the case is the recent addition of right-hand-hitting outfielder Austin Slater.

In Danger of Falling into Platoons

Red-hot rookie Carter Jensen is mostly included here for a little shock-and-awe. We anticipated a platoon for him before the season and he hasn’t been great against southpaws, but he has started against the last two lefty starters as Salvador Perez has mostly been playing DH and first base. The Royals recently signed short-side platoon catcher Elias Díaz and he will earn the occasional start behind the plate.

Nolan Schanuel is actually a competent hitter against southpaws (career 98 wRC+ in 330 PAs). He’s had a rough run against them so far this season, but it’s a tiny sample. Angels manager Kurt Suzuki might want to see if Oswald Peraza is capable of playing first base. His at-bats will be curtailed as the Angels play more RHPs, but perhaps he would serve as the ideal platoon pairing with Schanuel at first base.

Matt Wallner was told he’d have the opportunity to run away with everyday at-bats. So far this season, he can’t hit lefties or righties. Wallner is hitting a mere .172 with the fourth-highest strikeout rate (36.8%) among qualified hitters. He is hitting the pine for Tuesday’s contest and I’d be shocked if he started against the next lefty starter (Patrick Corbin on Friday). Otherwise, the Twins face all righties this week.

We don’t want to get carried away with a one-month sample of limited handedness data, but these are hitters worth highlighting. Wilyer Abreu and Daulton Varsho are both holding their own against southpaws. Even a slight slump against lefties won’t keep Blue Jays manager John Schneider from benching Varsho against them. With Alex Cora out of the picture and a new Driveline-infused coaching staff, we can’t be sure about Abreu’s prospects on that front.

Jarren Duran’s wRC+ split is wild, but not in the way you’d expect — a 101 wRC+ against lefties and 19 against righties. He’s earned four times more PAs against righties, and his .286 BA against lefties is fueled by a .353 BABIP. He will probably play every day under this new regime.

Bryson Stott also has an odd reverse split (155 wRC+ vs. L, 33 vs. R), but digging into his splits page uncovers the true story. Stott has only had 12 plate appearances against lefties because he does not start against them, hence the 3-9 (three singles) and three walks will inflate his metrics. Stott has been ice cold. Let’s see if Mattingly can wake some of these bats up.

There are so many more players to dig into. I’ll do so at a later point in the season. The samples will be bigger, but still too small to extract meaningful insights. Baseball managers all operate their lineups differently, but platoons remain a big part of their strategy. The best way to get ahead of potential shifts in platoons is to track each team’s lineup daily and watch for trends.
