Carlos Zambrano, through June 1, had 4 quality starts out of 12. 3 of those QS's were with Blanco catching. Since the Barrett fight, Zambrano has 8 quality starts out of 8 starts. Barrett didn't catch any of them. Barrett caught 7 of the 8 non-quality starts, and the one Barrett didn't catch, Blanco caught him in a 5 1/3 inning, 2 run start that just missed being a QS. If ever there were an example of a pitcher and a catcher not getting along, that is it. Sample size. 12 starts proves nothing. If you would like to look at Barrett's stats catching the Cubs staff this year total, or over the last 3.5 seasons, they have been posted repeatedly, and don't support your argument. I'd bet that if you looked at Barrett's full 3.5 seasons catching Zambrano, any difference would be pretty small.
