Both Jeff Karstens and Jose Tabata exited Saturday night's 4-0 win over Milwaukee due to groin injuries.
Karstens injured his right groin after making a pitch to Norichika Aoki with two runners on and one out in the eighth inning. After being evaluated by the training staff, Manager Clint Hurdle elected to remove the right-hander and call upon the bullpen to finish off the eighth inning and remainder of the game.
Karstens missed two months of the season due to a right shoulder injury in late April. But while making a rehab appearance in Altoona, the right-hander was removed from the outing with a similar injury that Karstens said was much worse than what he felt on Saturday night. Karstens said he doesn't expect to miss any time with the injury.
