The thought first crossed my mind when Vazquez failed to step up his game against the Twins following Ozzie Guillen's unflattering comments.
At that point, Guillen had not lost faith in Vazquez; he had merely issued a challenge to his feeble-minded hurler. The Sox gave Vazquez every opportunity to prove his detractors wrong over the last month, with two starts on short rest (both disasters), and two games in domes in playoff environments (similar disasters). Needless to say he was unsuccessful. It's hard to believe that Guillen has any confidence remaining in Vazquez, no matter what his post-game comments may be, after 4 straight blown high-pressure starts.
If there's any short-term silver lining to Vazquez cratering yet again under high-pressure, it's that if the Sox are able to fight their way back into this series and force a game 5, there's no way he gets the call. It will be some combination of Mark Buehrle and Clayton Richard, who made Javy look like a chump with his 3+ innings of scoreless relief.
