Marlins pitcher Henderson Alvarez was able to toss a mostly pain-free session of catch Friday, and could throw a bullpen session by the end of the weekend, MLB.com reports.
Alvarez was already scratched from his scheduled start Sunday, after leaving his last start as a result of the injury. Manager Mike Redmond said Alvarez threw mostly without discomfort Friday, though it isn't clear when he might be able to return to the rotation.
"Pain was gone and just seemed to feel like he was ready to throw a bullpen, so that's good news," Redmond said. "It's just a matter now of when [he throws] it and how that goes as far as his availability for a start. We'll figure out where that will be."
