3 under-the-radar Brewers prospects to keep an eye on during Spring Training

The Milwaukee Brewers took the NL Central by storm in 2024, largely on the backs of their young players. Everyone, of course, expected great things from Jackson Chourio, but a career year from Willson Contreras and the emergence of Joey Ortiz propelled the Crew to the division crown. As Milwaukee begins its quest to go back-to-back, a new crop of young players are looking to make an impact in 2025.

A handful of Brewers prospects have the stuff to turn heads this spring

Most of the eyes in camp will be trained on the Brewers' Top 100 prospects, such as catcher Jeferson Quero and Jacob Misiorowski. However, the spring training squad also boasts a number of under-the-radar prospects who could break through this season.

Ernesto Martinez Jr., 1B

There’s a lot to like about Ernesto Martinez Jr. The 6-foot-6, 250-pound first baseman offers a good eye, improving power, and surprising speed for his size. He spent all of 2024 at Double-A, so he needs to prove his skills will translate to upper levels, but he could have a golden opportunity this season.

The Brewers’ first base situation is uncertain. Rhys Hoskins seems like he has one foot out the door, and Martinez has as much a chance to be the backup as Jake Bauers and Tyler Black. So far, Martinez is making the most of his opportunities in spring training. After striking out four times in his first two games, he adjusted and began to hit the ball with more authority. Martinez consistently posts the quickest bat speed and has launched at least three hits at more than 100 mph. (Several of the Brewers’ games have not had bat-tracking data.)

Martinez may also feel some pressure to perform this season as he will be eligible for the Rule 5 Draft if he is not added to the 40-man roster. He’s only on a one-year minor league contract, but even if he does not make the Majors, “El espectáculo” will certainly put on a show in Spring Training.

Logan Henderson, RHP

It’s not as if Logan Henderson is unknown. He’s widely regarded as one of the Brewers’ top prospects, ranked No. 6 by the Milwaukee Journal Sentinel and No. 11 by MLB Pipeline. However, the right-hander’s injury history and limited playing time will add some drama to his Spring Training outings.

So far, Henderson hasn’t missed a beat. His plus-changeup has been reliable, and he has demonstrated pinpoint control. In three innings over two outings, he has allowed just two hits and produced five strikeouts.

After zooming from Rookie Ball to Triple-A in 2024, Henderson seems likely to make his big-league debut this season. He could make some starts, given the question marks around Brandon Woodruff and DL Hall’s injury recovery, but his high velocity and wicked change may fit more naturally in the bullpen. Henderson has only pitched 173 ⅔ innings since being drafted in 2021, so a lighter relief workload may benefit him.

Anthony Seigler, 2B/C

While Caleb Durbin is the likeliest candidate to fill a utility bench role coming out of spring training, Anthony Seigler may get more buzz in camp by virtue of his fascinating history. Drafted by the Yankees out of high school, Seigler drew attention for his ability to do literally everything. He was a switch-hitter, switch-pitcher, infielder, outfielder, and catcher. Ultimately, he has settled on middle infield and catcher as his primary positions.

The Brewers signed Seigler to a minor league contract this offseason, and he could be an interesting player to watch this spring. He battled injuries for much of his tenure in New York’s farm system, and a change of scenery could help him fulfill the promise that earned him a first-round selection.

Seigler has been getting reps at both second and catcher, but if he sticks with the Crew, he will likely fill a middle infield role. With Willy Adames gone, he could find a place for himself in the mix of potential replacements.
