Every team has now had its first full-squad MLB spring training 2025 workout, so 2025 Fantasy baseball draft season is officially here. The first spring training games between the Cubs and Dodgers unfolded on Thursday and Friday with the Cubs winning both, and these teams will also get the regular season underway with a series in Tokyo beginning on March 18. Most of the league’s notable free agents have found a home, including Pete Alonso, who agreed to return to the Mets on Feb. 12 on a two-year, $54 million deal that includes an opt-out after the first season. Alex Bregman, meanwhile, agreed to a three-year, $120 million deal with the Red Sox on Feb. 15.

The SportsLine model is powered by the experts who powered projections for all three major Fantasy sites. They are sharing their 2025 Fantasy baseball rankings and cheat sheets, helping you find Fantasy baseball sleepers, breakouts and busts long before your competition.

Top 2025 Fantasy baseball sleepers
One of the 2025 Fantasy baseball sleepers the model is all over: Diamondbacks first baseman Josh Naylor. A former first-round pick of the Marlins who debuted with the Padres in 2019, Naylor finally broke through with the Guardians over the last few seasons. His time in Cleveland culminated with a 31-homer, 108-RBI season last year, and he made his first MLB All-Star appearance.

Top 2025 Fantasy baseball breakouts
One of the 2025 Fantasy baseball breakouts the model is jumping on: Nationals outfielder Dylan Crews. A top-10 MLB prospect last season, Crews made his Major League debut in 2024 and showcased impressive skills in a short stint in Washington.

Top 2025 Fantasy baseball busts
The model has pinpointed Dodgers pitcher Yoshinobu Yamamoto as one of its biggest busts for 2025. Despite a successful rookie season, concerns about further injuries could diminish his Fantasy value.
