TORONTO — Tuesday afternoon might not have been rock bottom but, to borrow from an old saying, the Yankees can see it from here.

After a hideous sixth-inning implosion cost them Monday night, the Yankees were simply hideous overall in a 12-5 loss to the Blue Jays in front of a wired Canada Day sellout crowd of 41,129 at Rogers Centre.

The Yankees (48-37), coming off a losing month of June (13-14), have lost 12 of their last 18 games. Their offense, the main culprit in that stretch, went 2-for-17 with runners in scoring position with 11 left on base (one of those hits, by Giancarlo Stanton, came in garbage time in the ninth).

The Yankees, who saw a catcher’s interference call against J.C. Escarra help spark Toronto’s five-run bottom of the seventh, highlighted by George Springer’s grand slam off Luke Weaver that turned the game into a laugher, lead the AL East by just one game over the Blue Jays.

Springer, who implemented his share of torture against the Yankees during his time with the Astros, went 3-for-4 with two homers and seven RBIs.

It is difficult to rank any loss as being worse than a previous one, so Tuesday’s stands alone in this regard: Of all of the Yankees’ bad losses of late, this was the most recent.

“We’re not playing our best baseball by any means,” Weaver said. “The concern is not necessarily high in my opinion. We’ve got a great offense, great pitching and great fundamentals out there on the field. So it’s going to click together.”

It seems to have clicked together for the Blue Jays (47-38), who have the third-best record in the majors since May 8 at 31-18. They did their best to hand the Yankees the game in the top of the seventh, committing back-to-back errors that allowed the visitors to tie it at 4-4.

It came apart quickly.

Aaron Boone went to on-fumes reliever Mark Leiter Jr. (4-6) to replace Max Fried, who was at 99 pitches. After retiring Myles Straw, Leiter allowed a single to Andres Gimenez, whose three-run homer off Fried in the fourth inning gave Toronto a 4-2 lead, and a walk to Tyler Heineman followed.

Managing like it was October, Boone went to his best reliever, Weaver, to face pinch hitter Addison Barger. Weaver struck out the infielder on a check swing, but the Blue Jays challenged, contending Barger, as he checked his swing, connected with Escarra’s glove.

After a brief review, Escarra was called for his second catcher’s interference infraction in two days, this one loading the bases. Springer soon unloaded them by hammering Weaver’s 2-and-1, 96-mph down-the-middle fastball for a grand slam that made it 9-4.

Although both Boone and Weaver said afterward they would like to see the rule tweaked so that catcher’s interference can’t be called on a check swing, Escarra said the responsibility is ultimately his.

“You know he wasn’t going to swing, but at the end of the day I shouldn’t have been too close like that,” Escarra said. “Going forward, I really have to make it a priority to not getting too deep in there.”

Fried came in having made 10 starts this season after a Yankees’ loss, going 8-1 with a 0.93 ERA in those games, but the lefthander, though not bad on Tuesday, did not have quite the same stuff. Fried, now with a 2.13 ERA, allowed four runs, three hits and two walks over six innings, allowing multiple homers in a game for only the second time this season (he’s allowed nine in 18 starts).

Jasson Dominguez’s two-out, two-run single in the first off Kevin Gausman made it 2-0, that lead lasting until the fourth when Springer led off with a homer. After two straight outs, third baseman Jazz Chisholm Jr. didn’t aggressively charge a Davis Schneider grounder, then pulled Goldschmidt off the bag with a wide throw, the sequence scored an infield hit. Fried walked Myles Straw, then threw a 1-and-0, 94-mph sinker with too little movement that Gimenez blasted to center for his fifth homer.

“I have to do my job to be able to get out of that and keep making pitches,” Fried said of Chisholm not making the play on Schneider. “I can’t walk the next guy and then left a sinker that was flat up [in the zone], and a good hitter made me pay.”
