Chris Denorfia hit a go-ahead RBI single in the seventh inning to lift the San Diego Padres to a 3-2 victory over the San Francisco Giants on Tuesday night.
The Giants scored more than four runs for just the fourth time in 22 games but still lost and fell a season-high nine games under .500. San Francisco also has the worst record in the majors (17-34) since May 13.
Todd Frazier had an RBI single and a three-run homer off left-hander Mike Kickham (0-3), who has been hit hard in each of his three major league starts.
The Miami Marlins beat the San Francisco Giants 6-3 on Friday night for their ninth straight win at AT&T Park.
The San Francisco Giants have called up catcher Hector Sanchez and right-handed reliever Jake Dunning. To make room for the newcomers, San Francisco sent first baseman Brett Pill to Triple-A Fresno.
