Reynaldo Lopez was sharp over seven innings to continue his late-season surge and lift the Chicago White Sox over the Baltimore Orioles 2-0 on Saturday night.

The 24-year-old Lopez (6-9) has a 1.10 ERA over his past five starts. He struck out six and allowed four hits and a walk this time to help Chicago to just its sixth winning streak of at least three games.

Yolmer Sanchez broke a scoreless tie with an RBI double in the sixth, chasing rookie Yefry Ramirez (1-6) from his longest big league outing with two outs. Avisail Garcia added his 18th home run in the ninth.

Caleb Frare retired two batters in the eighth and Juan Minaya got the last four outs for his first save.

Lopez was acquired from Washington after the 2016 season in the trade that sent outfielder Adam Eaton to the Nationals. The hard-throwing right-hander has been inconsistent since the deal but been excellent down the stretch of his first full major league season.

He retired 13 out of 14 batters before Renato Nunez singled in the fifth and became the first runner to reach second on Lopez's wild pitch. DJ Stewart popped out to end the threat.

Two innings later, Lopez worked out of a two-on, one-out jam. He fanned Tim Beckham with a curveball to end a 10-pitch at-bat, then pumped his fist as Nunez popped his 104th pitch to second.
