Â
Current Level: Triple-A
2025 MiLB stats: 130 G, .261/.363/.465, 17 HR, 34 SB
The Milwaukee Brewers have invited recently acquired infield prospect Jett Williams to big-league spring training. Williams was sent to Milwaukee alongside right-hander Brandon Sproat in the deal that sent right-hander Freddy Peralta to New York. Williams was viewed as the top prospect in the Mets system prior to the trade and now sits as the No. 3 prospect in Milwaukee (on MLB.com), trailing only Jesus Made and Luis Pena. Last season, Williams began the campaign with Double-A, where he posted a strong .281/.390/.477 slash line with 29 doubles, 10 home runs, 32 stolen bases.
He was then promoted to Triple-A Syracuse, where he took a slight step back, carrying a lower .209/.285/.433 line with seven long balls across a 34-game stint. Managers should expect Williams to open the season at Triple-A but should be in contention for an early MLB debut, especially if Joey Ortiz continues to struggle in the batter’s box.

Jesus Made, INF, Milwaukee Brewers
Current Level: Double-A
2025 MiLB stats: 115 G, .285/.379/.413, 6 HR, 47 SB
Milwaukee Brewers top prospect Jesus Made is being invited to big-league spring training. The 18-year-old shortstop is currently viewed as the No. 4-ranked overall prospect in the entire sport on MLB.com. He made his professional debut in 2024 in the Dominican Summer League and held a .331/.458/.554 with a strong 1.012 OPS. In 2025, Made began the season in Low-A but quickly progressed through the Milwaukee system, finishing the season in Double-A.

Across 83 games with Low-A, Made posted a solid .267/.373/.388 line with four home runs and 40 stolen bases. Through 32 games split between High-A and Double-A, Made took his level of play even higher, carrying an elite .331/.392/.474 line. While a 2026 MLB debut is unlikely, if he continues this current trajectory, he could make a strong case in the second half.

Current Level: High-A
2025 MiLB stats: 60 G, .218/.390/.320, 3 HR, 12 SB
The Kansas City Royals have invited catching prospect Blake Mitchell to spring training. Mitchell missed most of the first half of the 2025 season after suffering a broken wrist in February. However, once he returned to action, the top prospect struggled to find his footing. The team’s No. 2-ranked prospect spent most of the campaign with High-A Quad Cities and posted an underwhelming .207/.372/.296 slash line with seventeen doubles, two home runs, and nine stolen bases.
During this stretch, he carried a 71:45 K:BB. In 2024, Mitchell spent most of the season with Low-A Columbia, where he hit .238/.376/.439 line across a 106-game stint. The No. 56-ranked prospect in baseball, according to MLB Pipeline, is not expected to compete for his MLB debut this season but is a name to watch in dynasty formats.
Â
Current Level: Double-A
2025 MiLB stats: 116 G, .278/.335/.388, 8 HR, 12 SB
Boston Red Sox top prospect Franklin Arias quickly progressed through the lower levels of the system in 2025 and is nearing his MLB debut. The shortstop, who is considered the team’s top prospect on MLB.com and the overall No. 24 in the sport, began the 2025 season with Low-A but reached Double-A Portland in the second half. With Low-A, Arias held a .346/.407/.397 line across a short 19-game stint.
He would spend most of his season with High-A Greenville, where he posted a .265/.329/.380 slash line with 21 doubles, six home runs, and seven stolen bases. He finished the season, posting a modest .685 OPS during his first 10 games at Double-A. Managers should expect Arias to open the season at Double-A and be in contention for a second-half promotion to Triple-A.
Â
Current Level: Double-A
2025 MiLB stats: 120 G, .238/.343/.348, 8 HR, 31 SB
The Milwaukee Brewers have invited shortstop prospect Cooper Pratt to big-league camp. Pratt is currently considered the No. 53 overall prospect on MLB.com and the No. 3-ranked prospect in the Milwaukee system. Pratt joined the Brewers in the sixth round of the 2023 MLB Draft but has progressed through the minor leagues fairly quickly. After a brief stint in the Arizona Complex League in 2023, Pratt would spend the 2024 season with Low-A and High-A.
Through 96 games, Pratt posted a .277/.362/.406 line with 15 doubles, eight home runs, and 25 stolen bases. In 2025, the Magnolia Heights HS product would spend the entire season with Double-A Biloxi, where he posted a .238/.343/.348 line with eight home runs and 31 stolen bases. Managers should closely monitor his development in camp, as he could begin the season at Triple-A.

Current Level: MLB
2025 MLB stats: 20 G, .298/.394/.474, 2 HR
Chicago Cubs catching prospect Moises Ballesteros appears poised to take on a larger role in the major leagues this season. Jordan Bastian of MLB.com notes that with outfielder Owen Caissie now in Miami, Ballesteros faces minimal competition for everyday at-bats and should be in a great position to take on a lead role early in the campaign.

Last summer, Ballesteros made his MLB debut and had success during his brief 20-game stint, holding a .298/.394/.474 line with two doubles, one triple, and two home runs. He spent most of the season with Triple-A Iowa, where the 22-year-old posted an impressive .316/.385/.473 line with an .858 OPS, 29 doubles, and 13 home runs. Given his projected role as the primary DH, Ballesteros carries sleeper appeal in all 12-team formats heading into 2026.
