PITTSBURGH — The Pittsburgh Pirates recently got a key member of their lineup back and he'll get a big opportunity in his next game.The Pirates have Ryan O'Hearn starting at first base against the Houston Astros in the series opener at Daikin Park on June 2, marking his first start in the field in 17 days.O'Hearn came off the 10-day injured list on May 31 and started at designated hitter in the series finale vs. the Minnesota Twins at PNC Park, a 9-3 win, where he hit a solo home run in his first at-bat back.The Pirates now have an important player that can feature at multiple positons and produce at the plate in O'Hearn, as they start a crucial road trip.O'Hearn's Return is Big for the PiratesThe Pirates missed O'Hearn's bat, but they also missed his defense too, as he has served as their main right fielder this season.O'Hearn started 32 games in right field before his injury, while also starting seven of 22 games at first base and four games at designated hitter.Apr 21, 2026; Arlington, Texas, USA; Pittsburgh Pirates first baseman Ryan O'Hearn (29) fields a throw to first base during the game between the Rangers and the Pirates at Globe Life Field.

Esmerlyn Valdez started five games there, before going back down to Triple-A Indianapolis, while Jake Mangum will make back-to-back starts there after O'Hearn's return.It's likely that the Pirates are trying to ease O'Hearn back into his outfield role, giving him opportunities at first base, where he is a strong fielder, and at designated hitter, building him back up to avoid triggering his injury again.The Pirates also have one of their best hitters back, who has slashed .294/.371/.479 for an OPS of .850, with 28 runs scored, 48 hits, six doubles, eight home runs and 30 RBI this season.O'Hearn's combination of contact and power and good splits against left-handed and right-handed pitchers make him a dangerous piece back in a Pirates lineup that has served as one of the best in baseball this season.
