Mark Buehrle allowed two runs over 7 1-3 innings to become the winningest pitcher since interleague play began, and the White Sox ran the Pirates' losing streak to 11 games by holding on to win 5-4 Thursday night.

Buehrle (5-6) was in control until being pulled with the White Sox leading 5-1 in the eighth, when the Pirates scored three times against three pitchers to get to within a run.

Pedro Alvarez, the Pirates' much-awaited rookie who made his major league debut Wednesday, struck out for the third time with runners on first and third to end the comeback. Alvarez went hitless in four at-bats, also grounding into a double play after the Pirates put two on with one out while trailing 3-0 in the fourth.
