SAN DIEGO (AP) - 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.
Nick Hundley drew a leadoff walk in the seventh from rookie reliever Jake Dunning, who was called up earlier in the day from Triple-A Fresno. Ronnie Cedeno followed with a single to send Hundley to third and bring on reliever Javier Lopez.
Denorfia lined a 1-2 pitch to left for the single that broke a 2-all tie.
Dunning (0-2), who made his major league debut in June, took the loss. Tim Stauffer (3-1) got the win with 1 2-3 innings of shutout ball.
Huston Street pitched the ninth for his 26th save in 27 chances.
Defending World Series champion San Francisco (61-77) dropped into last place in the NL West, one game behind San Diego.
