Brewers Prospects Top Mariners 7-3 in Spring Breakout Marquee Matchup

Luis Peña delivered the loudest moment of the Cactus League's most anticipated prospect showcase, crushing a three-run home run to lift the Milwaukee Brewers' prospects past the Seattle Mariners 7-3 in the Spring Breakout marquee matchup at American Family Fields of Phoenix on March 21.

All five of Milwaukee's top-100 prospects saw action in the game. Jesús Made (MLB Pipeline No. 3), Luis Peña (No. 26), Jett Williams (No. 51), Cooper Pratt (No. 64), and Brandon Sproat (No. 100) all took the field for the Brew Crew. Seattle answered with a roster that featured six top-100 talents of its own, headlined by shortstop Colt Emerson (No. 9), left-hander Kade Anderson (No. 21), right-hander Ryan Sloan (No. 33), outfielder Lazaro Montes (No. 43), second baseman Michael Arroyo (No. 67), and outfielder Jonny Farmelo (No. 78).

The game lived up to its billing through six innings. Mariners right-hander Ryan Sloan started against a prospect-packed Brewers lineup and cut through them quick, fast and in a hurry. Though nobody in the game officially reached 100 mph, Sloan maxed out at 99.5 mph, topping his 2025 velocity ceiling of 98.8 mph. Armed with an ideal power pitcher's build, Sloan worked through three innings, retiring all nine hitters he faced with three strikeouts, 24 of 39 pitches for strikes, and four whiffs including two on a sweeper.

Seattle grabbed the early lead. Jonny Farmelo, the No. 78 overall prospect, led off with a single to right-center, and Michael Arroyo followed. Cooper Pratt answered immediately with a web gem, ranging deep to his right, corralling a grounder in the 5.5 hole, and throwing across the diamond in time to nab Arroyo by a step. The Mariners still pushed across a run, but Milwaukee took the game over from there.

Jett Williams doubled and scored twice, Jesús Made went 1-for-2 with a walk in three plate appearances, and Luis Peña homered and drove in three runs. Made, who remains the jewel of Milwaukee's system as a 20-year-old Venezuelan shortstop, played second base in the game with Pratt holding down shortstop. According to Keith Law, Made is now listed at 221 pounds, more than 30 pounds heavier than last year, and while Law noted the weight gain drew some scrutiny, "it hasn't hurt his bat speed," evidenced by a 105-mph ground ball single among his plate appearances.

MLB.com highlighted the outing with a feature under the headline "Peña shows off pop with loud 3-run blast in Spring Breakout game."

On the pitching side, Brewers right-hander Jaron DeBerry showcased elite spin in his two-inning appearance, generating whiffs on 10 of 18 swings and going a perfect 3-for-3 on his curveball. His breaking pitches stood out as the best from any pitcher in the Brewers-Mariners game.

Jonny Farmelo delivered the hardest-hit ball of the game, a 112.4 mph single off Bishop Letson, one of the signature moments for a Seattle club that won the individual performance battle even while losing the score. Nick Becker, a newly drafted Mariners shortstop and younger brother of top 2026 draft prospect Eric Becker, entered in the second shift and lined a single off the glove of Brewers third baseman Andrew Fischer on a 92-mph fastball, one of the sharper moments from Seattle's late-game contingent.

Since Spring Breakout debuted in 2024, more than 200 participants have gone on to make their MLB debuts, with three taking home Rookie of the Year honors: Paul Skenes, Nick Kurtz, and Drake Baldwin. For Peña, Made, and the rest of Milwaukee's loaded infield depth chart, Friday's performance in Phoenix was the kind of audition that keeps that pipeline moving forward.
