The all-star break presents a critical moment for fantasy baseball managers to reassess their teams and consider stashing promising prospects for the second half of the season. A number of top prospects have had notable performances in the first half, providing a glimpse into their potential impact for 2025. Among them, Spencer Jones of the New York Yankees has emerged as a standout, showcasing a remarkable power surge in Triple-A with impressive stats: seven home runs, six steals, and a .362 batting average over his last 14 games. His ability to hit for power in Yankee Stadium makes him a tantalizing option, albeit with some strikeout concerns.

Owen Caissie of the Chicago Cubs is another prospect to monitor, as he has demonstrated significant improvements at the plate with a .333 average and 30-homer potential. However, his path to the majors might be blocked by established outfielders unless trades happen. Zac Veen of the Colorado Rockies and Bubba Chandler and Hunter Barco from the Pittsburgh Pirates also command attention as they continue to progress in their respective minor leagues. The next few months could be pivotal for these players as they seek opportunities for major league call-ups.
