Chicago scored the go-ahead run on a wild pitch during an intentional walk in the 10th inning as the White Sox posted a 6-4 victory over the host Los Angeles Angels on Wednesday.

The White Sox had runners on second and third with one out when Angels manager Mike Scioscia ordered reliever Kevin Jepsen (0-2) to intentionally walk Paul Konerko. Jepsen’s first pitch went well over the head of catcher Hank Conger and Alexei Ramirez scored the tiebreaking run.

Brent Lillibridge hit a sacrifice fly to score Adam Dunn with an insurance run to make a winner of Sergio Santos (2-0), who pitched two scoreless innings. Matt Thornton got the last three outs for his first save.

Chicago scored twice in the ninth against Jordan Walden to tie the score. A.J. Pierzynski singled for his fourth hit of the game to pull the White Sox within 4-3 and Omar Vizquel tied it with a sacrifice fly.

Vizquel also had a run-scoring double in the eighth when Chicago cut Los Angeles’ lead to 4-2.

Torii Hunter had an RBI triple in the first inning and singled in a run in the third off White Sox starter Jake Peavy, who made his first major league start in 10 months. Erick Aybar also had a run-scoring single in the third and Alberto Callaspo delivered an RBI single in the sixth for Los Angeles.

Peavy gave up four runs and seven hits in six innings in his return from major shoulder surgery in July. He struck out four and walked none.

Angels starter Tyler Chatwood allowed run and eight hits in 6 1/3 innings. Dunn’s third-inning homer was the lone run against Chatwood.

Dunn also had four hits for the White Sox.
