CHICAGO (AP) -- Barry Zito threw seven strong innings and the San Francisco Giants beat the Chicago Cubs 6-3 on Tuesday night for a sweep of a day-night doubleheader.
Zito (1-1) pitched for the first time since leaving his start on April 16 with a right foot sprain. He allowed four hits and two runs, leading the Giants to their seventh straight win.
Brian Wilson got his 24th save.
Nate Schierholtz had three hits and two RBIs to pace the San Francisco offense, and Brandon Crawford added two hits and two RBIs.
Rodrigo Lopez (0-2) -- pressed into starting duty after throwing out of the bullpen for most of the season -- allowed eight hits and four runs in 4 2-3 innings for the Cubs.
Pat Burrell and Aaron Rowand each drove in three runs as the Giants won the opener 13-7.
