I agree with most of the latter, but we were talking about Bello exclusively.
Said that, the major issue with Bello is in his mind and is not a minor thing by any means. He was ahead in the count 0-2 a couple of times in the 1st inning but ended up hitting and walking 2 batters. The rest is history. It is the story that has been repeating over and over again throughout his short career.
