Cobb (elbow) was taken off his rehab assignment to focus on his mechanics during bullpen sessions, Marc Topkin of the Tampa Bay Times reports.
The Rays recently moved Cobb's rehab outing to this week before officially taking him off the assignment Tuesday. There is still no word on whether the right-hander has suffered a setback, but the team wants to give him more time to work on his mechanics outside of a game atmosphere. Cobb can't pitch in a game until Monday, and will not likely return until late July at the earliest, barring any setbacks.
