SEATTLE (AP) — Rookie Michael Busch homered for the fourth straight game, Javier Assad struck out six and the Chicago Cubs beat the Seattle Mariners 3-2 on Sunday.

Reliever Adbert Alzolay picked off pinch-runner Julio Rodríguez to end the game after double plays ended two rallies. First-base umpire Doug Eddings initially called Rodríguez safe under first baseman Busch’s tag, but Alzolay knew the call would be overturned.

“I was kind of playing with the clock a little at that time,” Alzolay said. “As soon as I seen him kind of jumping, that’s when I made my move. ... I was super confident. As soon as I threw the ball, I saw Buschy (making the tag) and looking at his face, he goes, ‘Oh, yeah, I got it.’”

Busch’s two-run homer put the Cubs up 3-0 and helped them to their second straight win to take the series from the Mariners. The franchise record for consecutive games with a home run is five, held by four players, including current Cubs slugger Christopher Morel, who did it last season.
