SEATTLE — Daulton Varsho drove in the go-ahead with an RBI single in the top of the 10th inning, as the Toronto Blue Jays beat the Seattle Mariners 5-4 on Sunday.
Varsho's two-out hit off Mariners reliever Collin Snider (0-1) drove in automatic runner Vladimir Guerrero Jr. from second and sent the Blue Jays to a series victory over the Mariners, who have now dropped six consecutive series.
Chad Green (2-1) got the win. Génesis Cabrera pitched the 10th for his second save.
Victor Robles got the scoring started with a leadoff solo homer off Blue Jays starter José Berríos in the third, but Toronto tied it in the fourth when Bo Bichette led off with a ground-rule double against Mariners starter George Kirby, and scored on a one-out sacrifice fly from Alejandro Kirk.
Mitch Garver put Seattle back ahead in the fifth with a three-run homer, but George Springer tied the game back up at 4-4 with a three-run blast in the seventh off Mariners reliever Ryne Stanek.
''It was just a big spot,'' Springer said. ''I was happy to come through right there. I kind of blacked out a little bit. I know I was excited, and it was one of those things where it was just a big moment for us as a team, and I'm happy to help.''
Springer's homer led to loud cheers from the thousands of Blue Jays fans in attendance in Seattle.
''The support has just been phenomenal every time we come here," manager John Schneider said. ''It's a full weekend of baseball. Three close games, kind of similar teams I think too, and it was just awesome that the fans were here to kind of support us. We love coming here.''
