Marlins 5, Giants 0: Giancarlo Stanton homered and Tom Koehler threw seven superb innings as visiting Miami blanked San Francisco.

Koehler (4-3) bounced back from a dismal outing against the Los Angeles Dodgers by allowing only four hits and striking out seven for Miami, which improved to 4-6 on its 11-game road trip. Adeiny Hechavarria and Stanton had two hits apiece as the Marlins won for the 14th time in their last 18 games in San Francisco.

Hechavarria gave Miami an early lead with an RBI single in the second off Tim Lincecum (3-3), who allowed three runs while striking out six over six frames. Lincecum ran into trouble in the sixth, when Casey McGehee hit a leadoff double and Garrett Jones tripled before Jarrod Saltalamacchia lifted a sacrifice fly to left field.

Stanton extended Miami’s lead with a two-out solo blast in the seventh off David Huff, and pinch hitter Jeff Baker contributed an RBI single in the ninth. Stanton is batting .319 (22-for-69) with nine doubles, a triple, five homers and 12 RBIs in 17 career games at AT&T Park.

San Francisco, which has lost three of its last five, loaded the bases with two outs in the ninth against Kevin Slowey before Steve Cishek struck out Tyler Colvin for his ninth save and second in as many games. Hector Sanchez went 3-for-3 for the Giants, who were 0-for-6 with runners in scoring position.
