Seattle All-Star Julio Rodríguez, J.P. Crawford and Cal Raleigh each had two hits. The Mariners had won their previous four games.
Cobb worked efficiently most of the night and didn’t allow a runner past second base. He calmly escaped a jam in the sixth after Rodríguez’s deep fly to center glanced off Matos’ glove and fell in for a double. After Rodríguez was balked to third, Cobb struck out Teoscar Hernández then retired Mike Ford on a comebacker and got Eugenio Suárez on a groundout.
Rodríguez dropped a ball in center that led to an unearned run for San Francisco in the fifth. Rodríguez tracked down LaMonte Wade Jr.’s fly at the warning track but couldn’t hold onto the ball after running into the fence. Austin Slater, who walked and advanced to third on a Flores hit, scored easily on the error.
Brandon Crawford walked in the second and took third when Flores hit a sharp grounder that bounced off the third base bag and over Seattle third baseman Jose Caballero into left field. Wade’s sacrifice fly off Mariners starter Tommy Milone (0-1) drove in Brandon Crawford.
Milone, called up from Triple-A Tacoma before the game to take the rotation spot of injured Bryce Miller, struggled with his control and matched his career high of four walks. The lefty pitched with runners on base in each inning and allowed two runs (one earned) on four hits in 4 1/3 innings.
Giants second baseman Casey Schmitt made a stellar defensive play with a sliding backhanded stop on J. P. Crawford’s sharp grounder that had an exit velocity of 107.8 mph. Schmitt then threw to first for the easy out.
Mariners RHP Darren McCaughan was optioned to Triple-A Tacoma to make room for Milone. … RHP Penn Murfee (right elbow inflammation) was transferred to the 60-day Injured List.
Mariners All-Star RHP George Kirby (7-7, 3.21) faces the Astros on Thursday in the opener of a four-game series in Houston leading into the All-Star break.
