LOS ANGELES -- Mookie Betts hit a two-run double in the eighth inning on Saturday night, giving the Los Angeles Dodgers outfielder 105 RBIs, the most ever by a leadoff hitter.

During a 7-0 victory over the rival San Francisco Giants, Betts doubled to center off San Francisco's Ross Stripling, scoring Austin Barnes and David Peralta and extending the Dodgers' lead to seven runs. He doubled in the seventh, too, and walked twice for the NL West champions.

Entering the game, Betts had been tied with Charlie Blackmon of the Colorado Rockies at 103.

"There's been a lot of great leadoff hitters and for him to be number one is pretty remarkable," Dodgers manager Dave Roberts said. "It seems like every night we're eclipsing milestones as individuals."

The NL West champion Dodgers clinched a first-round bye in the postseason with the victory. They also earned their 95th win and 15th shutout, tied for second in the major leagues behind Seattle's 16.

San Francisco has lost seven of nine and been outscored 57-32 with one game remaining on its road trip.
