Cobb (elbow), who reportedly "felt good" after throwing a two-inning batting practice session Saturday, will throw another bullpen session Tuesday, Marc Topkin of the Tampa Bay Times reports.
The session will serve as a litmus test of sorts for Cobb, with a determination on whether he's ready to return to pitching in minor league games expected soon thereafter. The 28-year-old was temporarily taken off any rehab appearances after a pair of rough outings and has instead been working in bullpen sessions with the goal of building up his stamina and improving his mechanics.
