Brad Bergesen held a pretty good White Sox lineup hitless for 3 2/3 innings and might still be working on a short no-hitter if Ty Wigginton had not made an error on a sharp grounder by Carlos Quentin with one out in the fourth.
Bergesen walked the leadoff man in the inning and struck out Josh Fields before the error. He also struck out Jim Thome before Jermaine Dye hit a sharp single through the middle for a run and Paul Konerko followed with a line single to right that scored Quentin. The inning ended there when Dye was thrown out by Nick Markakis trying to go from first to third.
Finally a fundamental mistake that worked in the Orioles favor. Dye broke the unwritten rule that you never make the first or last out of an inning at third base.
