White Sox 4, Angels 2: A.J. Pierzynski belted a go-ahead, pinch-hit two-run homer as host Chicago won for the fourth time in five games.

Pierzynski has homered in five consecutive games and his seventh-inning blast off Jason Isringhausen (3-2) barely cleared the wall in right-center field to erase a 2-1 deficit as the White Sox maintained a 1 1/2-game lead in the American League Central over the Detroit Tigers.

Alexei Ramirez added a run-scoring triple in the eighth on a drive into the gap in which Angels right fielder Torii Hunter nearly made a spectacular reaching grab.
Addison Reed struck out two in the ninth for his 19th save in 22 opportunities.

The Angels took a 2-1 lead the lead in the top of the seventh when Peter Bourjos walked against Nate Jones (5-0) and moved to second on a sacrifice bunt by Bobby Wilson. After Mike Trout struck out, Hunter smacked a single to left field to score Bourjos.

Los Angeles manufactured a run in the fifth after Maicer Izturis started the inning with a single off the right leg of White Sox starter Francisco Liriano. Izturis moved to second on a bunt single by Bourjos, and to third on a sacrifice bunt by Wilson before Trout drove in the run with a sacrifice fly.

Liriano left the contest after the inning with a quad contusion. He gave up one run and four hits before exiting.

Chicago tied the score in the sixth on a line-drive homer to left by Kevin Youkilis, his third long ball in two games.

Angels starter Dan Haren allowed one run and four hits in six innings.
