Cobb has resumed playing catch and is a week away from starting to throw off the mound, Marc Topkin of the Tampa Bay Times reports.
Currently on the 15-day DL, the 28-year-old right-hander's rehab from May 2015 Tommy John surgery continues on schedule, and absent any setbacks, could result in a mid-season return. Cobb has compiled a 35-23 record and 3.21 ERA over 81 starts in his four-year major league career.
