The top 25 fantasy baseball prospects for 2026 include Kevin McGonigle, Konnor Griffin, and Kevin Wetherholt. These players are among several who have a good chance to make a fantasy impact before the end of the year. Despite being considered among the top 25 overall prospects, this list only considers the potential for fantasy success in 2026. Wetherholmt, who was excellent in 2025 with a.931 OPS, 17 homers and 23 stolen bases while splitting time in Double-A Springfield and Triple-A Memphis, could help in multiple categories. However, there are concerns that he might struggle against MLB pitching due to his position as a backup. McLean, a 24-year-old starting pitcher, has one of the most complete arsenals of complete pitching tools in the sport.
