Rays vs Brewers Preview

After facing southpaw Kyle Harrison on Monday, the Rays will deploy their strong-side platoon lineup against Brandon Woodruff.

Yandy Diaz and Junior Caminero are both nearly 40% better than league average against left-handed pitching, but they are also the Rays' only two above-average bats against lefties.

Conversely, while Caminero and Diaz are closer to 25% above average against righties, they are accompanied by above-average left-handed bats (Jonathan Aranda and Jake Fraley) and three other average depth pieces (Cedric Mullins, Chandler Simpson, and Richie Palacios), with Chandler Simpson's game-changing speed also on display against right-handed pitching.

Rays' lefty Shane McClanahan also forces the Brewers into their lesser split; Milwaukee's current platoon lineups carry an average 103 wRC+ against righties, compared to a 99 wRC+ against lefties.

McLanahan (projected FIP range 3.34 to 3.91; projected K-BB% of 15.5% to 20.1%) will make his first major league start since 2023 (career 3.63 xERA, 3.15 xFIP, 20.9% K-BB%) following Tommy John surgery and a subsequent triceps injury.

He pitched well in spring (13 IP, 8 H, 3 R, 5 BB, 15 K), getting up to 73 pitches in his final outing on March 20, while touching 95 mph on his fastball in his fifth and final inning.

And he generally projects better than Brandon Woodruff (projected FIP range 3.64 to 4.12; projected K-BB% of 17.0% to 19.3%), who made 12 starts last season, after returning from his own lengthy recovery (surgery in October 2023) following a shoulder injury.

Woodruff (2.20 xERA, 3.24 xFIP, 26.8% K-BB% in his 2025 sample) had an odd ramp-up this spring, tossing just five total innings across two outings while going from 32 to 62 pitches but prioritizing caution.

Rays vs Brewers Picks

The leash for either starter may be around 80 pitches on Tuesday.

The bullpens, baserunning, and defensive quality are roughly even on either side.

Still, I do give Tampa Bay the edge, specifically in the first five innings (F5), in the starting pitching matchup, in their respective handedness, and in their offensive splits.

Bet the Rays to even money on the F5 moneyline, or play their full game line to +108, in what I project as a coinflip contest.

Pick: Rays ML (+118, FanDuel | Play to +108)
