TORONTO — Home runs have been coming in bunches for the New York Yankees in recent games, and they got a bunch more Saturday.
The Yankees tied the franchise record with four homers in an inning. Gardner led it off with a home run and then with two outs, Holliday, Castro and Gregorius connected in succession.
"It's pretty impressive, a lot of fun to be a part of," Gardner said.
It was the 25th multihomer game of the season for New York, second in the majors to Tampa Bay (26). The Yankees have gone deep in 13 of their past 15 games, hitting 25 homers in that span.
"We're getting it from all spots in the lineup, which is really nice," manager Joe Girardi said.
All eight of New York's hits were for extra bases. The Yankees had four doubles, with Castro, Gregorius, Aaron Judge and Aaron Hicks hitting them.
Jason Grilli became the first reliever in Blue Jays history to allow four homers in a single inning. He declined to speak to reporters following the game.
Blue Jays manager John Gibbons stuck with Grilli as long as he could because, as he said, "our guys in the `pen are running on fumes right now."
This was the fourth time the Yankees have hit four homers in an inning — they last did it Oct. 1, 2012, against Boston. They first did it in 1977 at Toronto against the expansion Blue Jays, with Cliff Johnson connecting twice and Lou Piniella and Thurman Munson once each.
Montgomery (3-4) gave up three singles in six innings, striking out five and walking three for his first win since May 6 against the Cubs.
"The curve was my best pitch today," he said. "I got it for strikes and then expanded the zone a little bit and got them to swing over it."
The rookie lefthander lasted just 41/3 innings in his previous outing, May 29 at Baltimore.
"I thought Monty threw the ball really, really well," Gardner said. "It's a lot of fun for us to play behind him and watch him continue to get better."
The Blue Jays are 3-9 against left-handed starters this season.
Joe Biagini (1-4) allowed three runs in a career-high seven innings.
"We didn't score him any runs, obviously, but he had it all working," Gibbons said.
Hicks and Judge hit back-to-back RBI doubles in the third. Biagini set down 10 straight before Castro and Gregorius doubled in the seventh.
Toronto put runners at first and second in each of the second, third and fifth innings but came up empty each time. The Blue Jays finished 0-for-7 with runners in scoring position.
Robinson Cano, Curtis Granderson, Russell Martin and Mark Teixeira were the four Yankees who homered in the same inning against the Red Sox in 2012. Cano, Granderson and Martin connected off Clay Buchholz and Teixeira homered off Alfredo Aceves.
Yankees: OF Jacoby Ellsbury (concussion) has been shut down after suffering headaches and will visit a neurologist when the team returns home Monday. ... LHP Aroldis Chapman (shoulder) threw a light side session Saturday. He'll throw one more side session before a simulated game next week. Chapman is expected to return by mid-June.
Blue Jays: C Russell Martin (neck) was held out of the lineup for the third straight day but hopes to return Sunday.
Yankees: RHP Luis Severino (4-2, 2.93) has allowed just two earned runs over his past three starts, covering 191/3 innings. New York is 6-4 when Severino starts.
Blue Jays: RHP Marcus Stroman (6-2, 3.28) is 5-0 with a 2.96 ERA in his past eight starts, and has won his past three. He's unbeaten since April 18 against Boston.
