Milwaukee Brewers infield prospect Jett Williams is trending towards beginning the 2026 season at Triple-A. While Williams appeared in a good position to crack the Opening Day roster following the trade that sent Caleb Durbin to Boston, the Brewers quickly signed veteran infielder Luis Rengifo, who is now penciled in to be their primary third baseman. While Williams has taken reps at the hot corner alongside his typical position at shortstop in camp, he will likely begin the season with Triple-A, where he can earn everyday at-bats. Williams joined the Brewers earlier in the offseason in the trade that sent right-hander Freddy Peralta to the Mets. Last season, Williams made his Triple-A debut in the New York pipeline and held a .209/.285/.433 line with seven long balls and two swiped bags over a 34-game stint. While he could still carve out a role, managers should expect the top prospect to begin in the season in Nashville.

Miami Marlins left-handed pitching prospect Robby Snelling may not be a lock to make the Opening Day rotation. Earlier in camp, the Marlins announced that veteran Chris Paddack would be joining the rotation, which gives Snelling one fewer starting position. Additionally, Max Meyer and Braxton Garrett are both fully healthy in the early stages of spring training. Both would have the edge over Snelling, given their previous MLB experience. As a result, Snelling currently sits as the team's No. 6 starter, on the outside of the five-man rotation. Last summer, Snelling looked quite comfortable in his first taste of Triple-A, logging 63 2/3 innings to the tune of a 1.27 ERA, 0.99 WHIP, and an 81:17 K:BB. Managers should continue to monitor his status, but it appears the 22-year-old might be ticketed for Triple-A to begin the season if the Marlins opt to deploy a five-man rotation.

Philadelphia Phillies right-handed pitching prospect Andrew Painter is in serious consideration for one of the final spots in the Phillies starting rotation. With Zack Wheeler (elbow) on the shelf to open the season, the team's top pitching prospect appears to be in serious consideration for one of the final spots. However, given his struggles last season, the team could turn to a veteran option for the short term. Last summer, Painter made his return from Tommy John but stumbled in his first look at Triple-A. After not pitching since the 2022 season, the former first-round pick logged 106 2/3 innings to the tune of a 5.40 ERA and a 1.55 WHIP. While he showed solid strikeout upside, tallying 111, he served up 46 free passes. Managers should continue to keep an eye on his development as he could hold some short-term upside in deeper formats if he were to earn a taste of the big leagues to begin the season. However, if these command issues linger in spring training, the Phillies may opt to keep him at Triple-A.

Minnesota Twins outfield prospect Walker Jenkins is a name to closely monitor in spring training as he could compete for an early MLB debut. The 20-year-old is currently viewed as MLB.com's No. 10-ranked prospect and Minnesota's No. 1 prospect. Last summer, Jenkins began the campaign with Double-A but was able to reach Triple-A, where he spent most of the second half. With Double-A, Jenkins held a .309/.426/.487 line with a strong .913 OPS. During his first 23 games with Triple-A St. Paul, the budding star did not look overmatched as he held a .242/.324/.396 line with six doubles, two home runs, and four stolen bases. While Byron Buxton is locked in as the team's center field, Jenkins could carve out a role in right field, sharing time with Matt Wallner or taking the lead job in left field over Austin Martin and Alan Roden. For now, Jenkins is a top name to watch in five-outfielder formats.
