I hear pitching a baseball causes wear and tear on a pitcher's arm, perhaps they should tell Cigrani, Stephenson, Corcino, etc... to throttle it back and only throw 40 pitches a night.

Billy has not mastered the art of the steal. Oh sure, he's got great speed which turns a stolen base attempt into a success at an acceptable rate, but he's still got pitcher moves to learn, catcher pop times, etc... The guys he's facing in AAA now, are some of the pitchers and/or catchers he'll be attempting to steal a base off of in the show. He doesn't need to attempt a steal just to attempt a steal, but he needs to harness the finer points basestealing.
