The drive, which drove in the last run in the Royals' 5-2 loss, was his eighth this season and the 159th of his 11-year big league career.
Kansas City's Alex Gordon broke Major League Baseball's season home run record with 12 days to spare, hitting the 5,694th long ball of 2017 on Tuesday night.
Gordon's home run off Toronto's Ryan Tepera broke a mark set in 2000 at the height of the Steroids Era. The drive, which drove in the last run in the Royals' 5-2 loss, was his eighth this season and the 159th of his 11-year big league career.
"A pretty cool thing to be a part of," Gordon said. "I didn't hit many this year, but I guess I made one count."
It was the 17th home run of the night in the major leagues and came just after Detroit's Alex Presley tied the record when he connected at home against Oakland's Daniel Gossett.
Gordon said he heard talk of the record on a clubhouse television after Toronto's Darwin Barney homered in the sixth.
"I was kind of aware that we were getting close to it," he said. "After I walked back to the dugout. I kind of forgot about it."
Holding the ball he hit over the right-field wall, Gordon said he didn't plan to keep the historic memento or anything else from the game.
"I'm going to give it to Cooperstown," Gordon said. "I figured they'd probably have much more reason to have it than I do. I don't really want to remember too much about this season, so I'll probably just give it away and let them take care of it."
There were 5,610 homers last year, an average of 2.31 per game, and this year's average of 2.53 entering Tuesday's action projects to 6,139. That would be up 47 percent from 4,186 in 2014.
"I don't know what to make of it," Royals manager Ned Yost said. "Guys are bigger and guys are stronger. but so are the pitchers. There sure are a lot of home runs being hit."
Blue Jays manager John Gibbons has noticed the surge in homers but doesn't have an explanation.
"It really looks like the ball is flying," he said.
Power subsided after the start of drug testing with penalties in 2004. The home run average dropped in 2014 to its lowest level since 1992, then started rising during the second half of the 2015 season.
