Marlins' Braxton Garrett: Going through dead arm phase

Marlins manager Skip Schumaker said Monday that Garrett (shoulder) experienced a "dead arm" after his last bullpen session, Jordan McPherson of the Miami Herald reports.

The issue isn't related to the left shoulder injury which has kept Garrett out all season, but it nonetheless could prevent the left-hander from making his season debut this week. The southpaw threw 86 pitches in his second rehab start with Triple-A Jacksonville this past Friday, and his return from the 15-day injured list appeared imminent. Garrett will undergo testing on his arm just to be safe, so it's no longer a lock that he'll rejoin the rotation this week.
