EDGE Analysis

Miley threw a 50-pitch bullpen session Friday, and he tossed a similar number of pitches while facing live batters Wednesday. It's possible the southpaw begins a rehab assignment soon, but the Cubs will wait and see how he feels Thursday before determining the next steps in his recovery process.
