Overview
- O'Hearn left Friday's game at Cincinnati after straining his left quadriceps while running to first and was placed on the 10-day injured list with a club estimate of six to eight weeks out.
- Pittsburgh recalled right-hander Isaac Mattson, activated catcher/first baseman Rafael Flores Jr., and optioned righty Antwone Kelly as immediate roster changes to cover O'Hearn's spot.
- The 33-year-old has been a primary run producer this season, batting .270 with 17 home runs and 69 RBI in 96 games, so his absence removes a key right-handed bat from the middle of the lineup.
- Teammates reacted emotionally to the loss and O'Hearn said he is frustrated by recurring quad issues after a shorter right-quad strain in May that he recovered from quickly.
- With the club near .500 and the Trade Deadline approaching, the Pirates could pursue an outside addition and will monitor returns from Spencer Horwitz and Oneil Cruz as short-term offsets to the roster gap.
