His command was the biggest issue not pitch selection or whatever BS some people keep saying. Simply he was falling behind in the count so often so he had to throw his fastball a lot to get back into the count. You aren't going to throw 2-0 sliders for strikes.
When he was ahead in the count he used his breaking ball so lets not go all crazy. Whats with the personal attacks on him anyway. Guy has a ton of passion and shows it, you should embrace someone like that. Not be sound like some loser on the Fan590 and say he should play the game the "white way"
