Lucas Giolito struck out 12 and the Chicago White Sox sent Baltimore to its 13th straight loss, beating the Orioles 3-1 Sunday.

Nick Madrigal hit a tiebreaking triple in the seventh inning as the White Sox completed a four-game sweep. The AL Central leaders have won six of seven and climbed a season-high 12 games over .500.

Giolito (5-4) allowed a run, three hits and three walks in seven innings. His 12 strikeouts were one shy of his career high.

The Orioles loaded the bases against Giolito in the sixth with a bunt single and two walks before Anthony Santander struck out and Maikel Franco fouled out. Baltimore scored just seven runs in the series.

Liam Hendriks pitched a perfect ninth for his 13th save and third in three games.

It was 1-all in the seventh when Tim Anderson singled, stole second, took third on a wild pickoff throw by Dillon Tate (0-3) and scored on Madrigal's triple. Yoan Moncada followed with an RBI single.

Anderson, Madrigal and Moncada had two hits apiece. DJ Stewart homered and Cedric Mullins had two hits for the Orioles.

Stewart homered off Giolito in the third.

Billy Hamilton hit a solo shot off Keegan Akin in the Chicago third. 

Akin allowed a run and five hits in 4 2/3 innings in his first start of the season.

Adam Plutko replaced Akin and walked Jose Abreu to load the bases in the fifth. Yermin Mercedes grounded out to end the inning.
