David Peterson encountered more traffic than the Bay Bridge in rush hour, but was resourceful enough Saturday night to record outs when the Mets needed them.

Mark Vientos' two-out, two-run double in the sixth inning gave the Mets the lead, and four Mets pitchers combined to make it stand up as New York made it two straight over the host San Francisco Giants with a 2-1 victory Saturday night.

Called upon to protect a one-run lead in the ninth, Edwin Diaz allowed a one-out double off the rightfield wall by Jung-Hoo Lee. After pinch hitter Mike Yastrzemski struck out swinging, Patrick Bailey hit a bullet to first base that was snagged by a leaping Alonso on the backhand to end the game.
