Whitley (elbow) mixed in some breaking balls in a 35-pitch bullpen session Tuesday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The 26-year-old reclamation project continues to progress in his comeback from May 2015 Tommy John surgery, and the introduction of breaking pitches represents another step in that process. Whitley generated an unsightly 5.02 ERA over 28 appearances with the Yankees over parts of two seasons, with 16 of those being starts. It's unclear how he'd be deployed by the Rays once fully healthy, which still remains a minimum of a month into the future.
