Zach brings it up within the first couple minutes of the interview. He said it's in his non-throwing shoulder and has virtually no impact. He's not concerned about getting surgery on it or anything like that - no threat at all to being ready for the season.

The biggest impact is that he can't do a bench press or other exercises that would put a lot of pressure on his left shoulder. He's doing band work / dumbells, etc, that isolates his throwing arm to make sure he builds his strength up.

The strength of his left arm is going to have zero impact on Zach's season.
