As the 2025 MLB season unfolds, several rookie prospects have made an impact after being called up. Chandler Simpson, an outfielder for the Tampa Bay Rays, has shown promise with his speed, recording two stolen bases in just 15 plate appearances. Nick Kurtz from the Athletics debuted strongly, hitting a home run and showcasing excellent plate discipline that could translate well in fantasy leagues. Luke Keaschall, a versatile infielder for the Twins, has already stolen five bases, indicating significant speed potential. Miami's Agustin Ramirez adds intrigue as a catcher with unexpected speed, while Caleb Durbin of the Brewers shows promise in batting average and stolen bases. Notably, Roman Anthony (Red Sox) and Bubba Chandler (Pirates) are prospects to keep an eye on for future call-ups.

As we approach the Super-2 threshold on May 9, 2025, fantasy managers need to keep an eye on key MLB prospects who could make an impact this season. Agustin Ramirez has been called up by the Miami Marlins, bringing power and speed potential that could redefine the catching position in fantasy leagues. With 25 home runs and 22 steals last year in Double-A, he provides a unique blend of skills. In addition, Jordan Lawlar of the Arizona Diamondbacks is on fire in Triple-A, boasting a .410 batting average and multi-positional versatility, making him a must-add in deeper formats.

On the pitching end, Bubba Chandler has been dominant in Triple-A, potentially the best pitching prospect poised for a call-up. However, Matt Shaw's early struggles with the Chicago Cubs might have fantasy managers reconsidering their holds on him. Overall, stashing these prospects could pay dividends as the season progresses, especially with several promotions expected before the Super-2 deadline.

The 2025 fantasy baseball season is heating up, and with it comes an opportunity to stash some key injured players who can be impactful upon their return. Players like Luis Gil from the New York Yankees, who posted a robust 3.50 ERA and 171 strikeouts in 2024, could be a great addition as he is expected back by late May. With Gerrit Cole sidelined, Gil's strikeout potential makes him a valuable stash.

Another exciting name is Eury Perez from the Miami Marlins, who showcased his talent with a 3.15 ERA and 108 strikeouts in 2023. After Tommy John surgery, he’s set to return in mid-to-late June, making him a worthwhile investment for patient fantasy managers. Masyn Winn of the St. Louis Cardinals is also projected to return soon, and his solid performance in 2024, with 11 stolen bases and 15 home runs, suggests he could provide immediate offensive support.

Jake Cronenworth, a versatile option for the San Diego Padres, is recovering from a rib fracture and is an intriguing pickup given his role in a strong lineup. Lastly, Connor Wong from the Boston Red Sox, despite a fractured finger, is expected to contribute significantly upon his return after a productive 2024 season. All these players present low roster percentages and can be great additions for teams with injured reserve spots.

For fantasy baseball enthusiasts looking to bolster their pitching staff, several intriguing streaming options are available for the upcoming week. Jeffrey Springs of the Athletics is set to face the White Sox and Brewers, showing promise with his increasing velocity. Grant Holmes, also rostered at 73%, faces favorable matchups against the Blue Jays and Twins, despite previous efficiency issues. Chaos characterizes Mitch Keller's outings with the Pirates, yet his potential for high strikeouts can be enticing with two starts against the Nationals and Guardians. Keep an eye on Tylor Megill of the Mets; he’s been solid this season, albeit with uncertainty about a second start.

Tomoyuki Sugano has shown efficiency for the Orioles and could benefit from a weak Guardians batting lineup. JP Sears of the Athletics, currently at 27% rostered, is worth a flier, especially against the struggling White Sox. Landen Roupp has swing-and-miss potential and would be a good addition in points leagues. Finally, Richard Fitts boasts quality starts and might emerge as a sleeper against the White Sox. As we enter this scoring period, these pitchers present a variety of opportunities for fantasy managers.
