Andy Pettitte slated for MRI on strained groin

Andy Pettitte felt discomfort during a bullpen session Tuesday and will undergo an MRI on the strained left groin that’s had him on the DL for almost a month. Pettitte finished his 40-pitch session at Yankee Stadium, but he admitted afterwards that he still wasn’t quite right. “I’m feeling good. I’m feeling better,” he said. “But when I reach back 100 percent, like I’m trying to get a batter out in a game, the groin area grabs.” If the MRI comes back clean, Pettitte could resume his rehab without a misstep. However, it’s definitely appearing less likely that he’ll rejoin the Yankee rotation prior to Sept. 1. Dustin Moseley has been filling in for him.
