CINCINNATI -- Injured reliever Luke Gregerson is nearing his Cardinals debut.
The right-hander was scheduled to make his fourth appearance for Class Advanced A Palm Beach on Friday, clearing a hurdle in the process that could see him join the club next week.
Gregerson needed to prove he could pitch on back-to-back days before rejoining the club. His appearance on Friday would be his second in as many days, after Gregerson threw a scoreless inning on Thursday.
Gregerson began the season on the disabled list with a left hamstring strain he sustained during the final week of Spring Training.
