In the ongoing 2026 fantasy baseball season, several players are valuable injury stashes for managers looking to bolster their lineups. Corbin Burnes, the ace pitcher for the Arizona Diamondbacks, is recovering from Tommy John surgery and is aiming for a return around the All-Star break in mid-July. His impressive 2.66 ERA and 63 strikeouts in 11 starts last season make him a strong candidate for a successful comeback. Similarly, Gerrit Cole of the New York Yankees is also on the mend from Tommy John surgery and is expected to return in June. His previous performance as a Cy Young winner adds to his potential value. Meanwhile, Jeremy Pena, shortstop for the Houston Astros, is currently on the injured list due to a hamstring strain and will be out for at least two weeks. Lastly, Christian Yelich, the outfielder for the Milwaukee Brewers, is dealing with a groin strain and could be sidelined for about a month, but his strong start to the season with a .314 batting average makes him a worthwhile stash. Fantasy managers should keep an eye on these players as they recover.
