Cobb (elbow) will throw his first live bullpen session on Saturday, Marc Topkin of the Tampa Bay Times reports.
Cobb has been recovering from Tommy John surgery last May, and has progressed far enough to have a live bullpen session. The starter is expected to throw three or four bullpen sessions on a five-day rotation, then will get some rehab starts in the minors. The right-hander is 21-12 over his two full seasons in 2013-2014 with the Rays over 49 starts, with a career 3.21 ERA and 1.19 WHIP.
