The 2025 MLB season has seen significant injury challenges for fantasy baseball managers, particularly involving key players like Bryce Harper, Jackson Merrill, and Matt Chapman. Harper, batting for the Philadelphia Phillies, has been sidelined with persistent wrist inflammation stemming from previous issues, making his timeline for return uncertain. Meanwhile, Jackson Merrill, the San Diego Padres' promising center fielder, is recovering from a concussion that occurred during a recent game, with a potential return this week if he passes concussion protocols. Lastly, Matt Chapman of the San Francisco Giants is dealing with a hand injury that has interrupted what was proving to be his best season yet.

Understanding these players' injury histories is crucial for fantasy managers. Harper's chronic wrist problems raise concerns about his long-term availability, while Merrill's concussion adds another layer to his injury-plagued season. Chapman, who was enjoying a career resurgence, faces a recovery timeline that could extend into the All-Star break, making his return vital for the Giants' push in the NL West. As the season progresses, monitoring these injuries closely will be essential for fantasy lineups.

Brady House, Samuel Basallo, and Andrew Painter are emerging fantasy baseball prospects worth monitoring as they could significantly impact your roster this season. With recent call-ups, House takes over at third base for the Washington Nationals, looking to capitalize on his power potential after a solid Triple-A stint. Meanwhile, Basallo of the Baltimore Orioles is making a name for himself with strong hitting metrics at Triple-A, hinting at a potential promotion soon. Andrew Painter, despite a slight dip in performance, remains a desirable stash due to his elite skills and the potential for a mid-season call-up with the Philadelphia Phillies.

House, currently 15% rostered, has shown promising offensive upside with 13 home runs in Triple-A this season and a recent upward trend in performance. His ability to secure a regular slot with the Nationals makes him a prime target for managers needing third-base depth. Basallo, also just 5% rostered, has been an offensive force in Triple-A, with an impressive slash line and good contact metrics. If he can secure a spot in the Orioles lineup, he could become a valuable fantasy asset. Painter, similarly at 5% rostered, has shown potential despite some recent struggles, and fantasy managers should consider stashing him for his potential impact later in the year.

He faces a struggling Miami lineup, enhancing his fantasy appeal.

Another pitcher to consider is Drew Rasmussen from Tampa Bay, boasting a 2.55 ERA. He’s consistently limited scoring opportunities and should perform well against the Baltimore Orioles.
