TORONTO (AP) — Marcus Semien hit a game-ending three-run homer in the ninth inning after Loudes Gurriel Jr. hit a tying grand slam in the eighth, and the Toronto Blue Jays rallied three times to stun the Oakland Athletics 11-10 Friday night.
Semien connected off Sergio Romo (1-1) for his 34th home run of the season, sparking a wild celebration at home plate.
Toronto’s Teoscar Hernández hit a tying two-run homer in the fourth before Oakland pulled away for an 8-2 lead. Gurriel’s slam capped a six-run eighth inning against Lou Trivino and Yusmeiro Petit to tie it again.
Blue Jays closer Jordan Romano (7-1) gave up Mark Canha’s two-run home run in the top of the ninth before Romo allowed a single, a double and Semien’s shot.
Vladimir Guerrero Jr. fueled the eighth-inning surge with an RBI single off Trivino, who left after loading the bases. Petit came on and walked Alejandro Kirk, then gave up a first-pitch homer to Gurriel.
Gurriel is the fourth player in Blue Jays history to hit three grand slams in a season, joining Carlos Delgado, Edwin Encarnacion and Darrin Fletcher.
Matt Olson reached on an infield single to begin the ninth. Romano struck out the next two batters, but Canha lined his first pitch off the foul screen in left, his 15th.
Tony Kemp added a two-run homer for the Athletics, his sixth.
Oakland’s collapse denied left-hander Sean Manea his first victory since July 28. After going 0-3 with a 9.90 ERA in five August starts, Manea allowed two runs and five hits. He walked none and struck out nine.
Blue Jays right-hander Alek Manoah allowed six runs and five hits in five-plus innings.
The benches cleared briefly after Manoah hit batters with consecutive pitches in the fifth. Josh Harrison flipped his bat in frustration after being hit with a high and tight fastball, and he was visibly angry after Manoah’s next offering hit Starling Marte on the side of the helmet.
Players came out of the dugout as trainers tended to a fallen Marte at home plate. Marte remained in the game and scored from first on Olson’s tiebreaking double. Skye Bolt replaced Marte in center field in the bottom half of the inning.
Manoah leads Blue Jays pitchers with 11 hit batters in 79 1/3 innings.
Many in the crowd of 14,843 booed Harrison in his two final plate appearances. Harrison made a show of bowing and tipping his helmet to fans behind the first base dugout after grounding out in the eighth.
Kemp chased Manoah when he connected in the sixth, his sixth.
Blue Jays: RHP Ross Stripling (strained left oblique) threw live batting practive before the game. Stripling’s next step will be a minor league rehab assignment.
Blue Jays: Toronto claimed INF/OF Jake Lamb on waivers from the Chicago White Sox and recalled LHP Kirby Snead from Triple-A Buffalo. Toronto designated RHP Conor Overton for assigment to open a 40-man roster spot for Lamb.
