Masset's long rehab assignment hit another snag, and he underwent an MRI. He was waiting to hear the results from team medical director Dr. Tim Kremchek.
"I had a minor setback after Tuesday's outing down in [Triple-A] Louisville," Masset said. "There's a little bit of soreness in my shoulder. Right now, we're just working on getting to the next step. That's where I'm at right now."
In nine Minor League games at three levels, Masset has a 5.59 ERA, including six games at Louisville. On Tuesday, he gave up three runs, four hits and two walks without retiring a batter.
"I never felt anything while I was pitching," Masset said. "It's been tough, especially with the way the team has been playing all year. My biggest objective this year is to just get healthy and get back on the mound and ultimately get back on the team down the stretch. Unfortunately, I've had a couple of setbacks here and there. It's not helping my cause."
