Normally I don't like to focus my attention on guys who grow up Cardinal fans and become White Sox. But I have to make an exception just this once.
This is the third time Mark Buehrle has thrown a complete-game shutout and faced the minimum 27 batters. Check it:
July 21, 2004. White Sox over the Indians 14-0. Buehrle 9 IP, 2 H, 0 R, 0 BB, 4 SO, 27 BF (Batters Faced)
April 18, 2007. White Sox beat the Rangers 6-0. Buehrle 9 IP, 0 H, 0 R, 1 BB, 8 SO, 27 BF
July 23, 2009. White Sox defeat the Rays 5-0. Buehrle 9 IP, 0 H, 0 R, 0 BB, 6 SO, 27 BF
And, although it must have seemed like a marathon outing, here's one more just to make us jealous Cub fans squirm:
August 3, 2001. White Sox best the Devil Rays 4-0. Buehrle 9 IP, 1 H, 0 R, 0 BB, 3 SO, 28 BF
I've been trying unsuccessfully to find a list of 9-inning games where the minimum 27 batters were faced by a pitcher or pitching staff. A comment on the latest baseball-reference blog claims that no other pitcher has duplicated Buehrle's feat, but I can't verify the fact.
Right now, I'm simply holding firm to the idea that it's a pretty safe bet. Buehrle is in a league all his own. Congrats.
