UPDATE (9:25 p.m. EST): Tonight's game has officially been postponed. No word yet on a rescheduling.
Armando Galarraga (3-1, 3.07) vs. 
Mark Buehrle (4-0, 3.30), 8:11 p.m. EST
Winning three of their last five games, the Tigers stop into Chicago for a two-game quickie against the division rival they just can't seem to beat. The White Sox are on a four-game winning streak, however, so maybe Detroit is catching them on a downturn.
Armando Galarraga has won one of his last three starts, and perhaps it's not a coincidence that his walk totals have increased during that period. In his last 16 innings, Galarraga's given up 11 walks. As you might expect, that's racked up his pitch counts and chased him from games earlier than the Tigers would prefer. And that doesn't look like the same pitcher that was so impressive last season (and in his first two starts this year).
Mark Buehrle appears to have regained his ace status in the White Sox starting rotation. Not only hasn't he lost a game this season, but he's working efficiently, keeping his pitch counts low, and walking very few hitters (nine in 30 innings). Buehrle also hasn't given up more than three runs in any of his five starts this year.
How does tonight's lineup look? Clete Thomas's 3-for-4 performance last night earns him another night of batting third. (The Cult is pleased.) Curtis Granderson, however, returns to his customary leadoff spot. Magglio Ordonez moves up to bat fifth, remaining as the designated hitter.
