Two developments on an otherwise light day at Cubs training camp Thursday highlighted the biggest baseball concern the Cubs face in a 60-game season, even if they’re able to keep their entire roster healthy and coronavirus-free.
Pitching depth.

And watching Jose Quintana play catch Thursday for the first time since surgery July 2 to repair a damaged nerve in his thumb was just one more reminder of how that depth has only become a bigger problem since then.
