EDGE Analysis

A left shoulder strain has kept Basso on the injured list all season, though he seemed close to a return after making three rehab appearances in the minors. However, a setback in his recovery puts him at risk of spending even more time on the IL. He's set to be re-evaluated within the next several days, at which point a new timeline for his recovery may be established.
