The San Francisco Giants supported Logan Webb with four home runs and the right-hander delivered six innings of two-hit ball Saturday in a 9-2 shellacking of the visiting Cincinnati Reds.

Evan Longoria, Thairo Estrada and Joc Pederson belted solo shots before Wilmer Flores broke the game open with a three-run blast, helping the Giants rebound from a series-opening 4-2 defeat on Friday night.

Webb (7-2) allowed the Reds' first run in the top of the second on a two-out single by Nick Senzel. A throwing error by third baseman Longoria had kept the inning alive.

The Giants then wasted little time claiming the lead for good, with Longoria smacking his seventh homer on Mike Minor's sixth pitch of the bottom of the inning before Estrada hit his sixth home run eight pitches later.

Darin Ruf had an RBI single and Longoria contributed a sacrifice fly in a two-run third, and when Tommy La Stella lashed a RBI double in the fourth, the Giants' lead had grown to 5-1.

Pederson made it 6-1 by leading off the fifth with his 17th homer, and Flores put a wrap on the rout with a three-run shot, his ninth of the year, in the sixth.

Flores' liner to left snapped a streak of nine straight solo homers by the Giants dating back to Austin Wynns' three-run blow in Atlanta on Tuesday.

The Giants' first six runs came off Minor (1-4), who allowed eight hits and two walks in his five innings. He struck out four.

Webb was pulled after his team's uprising in the sixth, charged just with the single unearned run. He walked two and struck out six.

The Reds' Brandon Drury hit his 15th homer, a solo shot in the eighth, to complete the scoring.

Flores and Pederson had two hits apiece for the Giants, while Flores and Estrada scored twice.

San Francisco outhit the visitors 9-5. The Reds had just one extra-base hit -- Drury's homer -- in their eighth loss in the last nine games.
