DETROIT (AP) — Jake Peavy pitched six innings without allowing an earned run — even remaining in the game after a rain delay of 2 hours, 42 minutes — and the San Francisco Giants routed the Detroit Tigers 8-2 on Friday night.

Pablo Sandoval homered for San Francisco, which is trying to chase down the first-place Los Angeles Dodgers in the NL West. The Tigers fell two games behind first-place Kansas City in the AL Central — and now trail Seattle by a half-game for the second wild card.

The Giants scored six runs in three innings against Rick Porcello (15-10) and led 6-0 when a severe storm came through downtown Detroit, delaying the game. When play resumed, Peavy (4-4) went back to the mound. He allowed two unearned runs in the fifth, but that was it.

Playing in Detroit for the first time since winning the World Series there in 2012, the Giants scored a run in the first, three in the second and two in the third. Porcello allowed five earned runs and 10 hits in three innings, and also dealt with an injury scare when a comebacker by Brandon Crawford hit his right foot in the third.

Porcello stayed in the game and got the third out of the inning. After the Tigers batted in the bottom half, the heavy rain moved in, with debris sailing around in the wind as the grounds crew overcame difficult circumstances to put the tarp on the field. Head groundskeeper Heather Nabozny injured her right knee and had to have an MRI. The team said she is out indefinitely.

Sandoval’s solo homer in the sixth — his 16th of the year — made it 8-2.

San Francisco opened the scoring on Sandoval’s RBI single in the first, and Travis Ishikawa added one of his own in the second. Angel Pagan’s run-scoring groundout made it 3-0, and Joe Panik’s infield single brought another run home.

Panik actually made the third out on that play in strange fashion. Second baseman Ian Kinsler’s throw got past first base, but catcher Bryan Holaday was backing it up. He threw to first, and Panik — who appeared to have turned ever so slightly toward second after overrunning first — was tagged out.

Peavy allowed six hits and struck out three.

Trainer’s Room

Giants: OF Michael Morse (strained oblique) received a cortisone injection, and the Giants hope he can return for the team’s next series, at home against Arizona.

Tigers: RHP Joakim Soria threw off a mound and hopes to throw batting practice Monday as he works his way back from a strained left oblique.

UP NEXT

Saturday’s game will start less than 13 hours after Friday’s ended, and San Francisco will send LHP Madison Bumgarner (16-9) to the mound. Detroit counters with LHP David Price (13-10), who has a career-high 232 strikeouts this season.
