Cobb (elbow) will make his next rehab start for High-A Charlotte on Thursday, Roger Mooney of the Tampa Bay Times reports.
The 28-year-old will try to build in his successful return to game action last Friday, when he fired a pair of scoreless frames. Cobb reported feeling both strong and mechanically sound following the outing, which came after a seven-day layoff from live action to work on the finer points of his delivery. He remains without an exact timetable for a possible ascension to the big league club, but another positive outing will certainly be a step in the right direction.
