Pinch-runner Breyvic Valera scored the tiebreaking run on a wild pitch in the eighth inning, and the Toronto Blue Jays beat the Chicago White Sox 2-1 on Monday night.

Valera ran for Reese McGuire after the Blue Jays catcher singled off Craig Kimbrel (2-4) to begin the inning. Valera took second on a wild third strike to Bo Bichette, advanced to third on a groundout, and scored when Kimbrel uncorked another wild pitch, this time to Teoscar Hernández.

"That was huge against one of the best closers in baseball," Blue Jays manager Charlie Montoyo said.

Tim Mayza (3-1) pitched a perfect eighth inning to earn the win, and Jordan Romano finished for his 12th save in 13 chances.

White Sox shortstop Tim Anderson sat for the third straight game because of soreness in his legs. Anderson could return Tuesday, manager Tony LaRussa said.

Toronto spoiled a strong outing by Chicago’s Lance Lynn and handed the White Sox their fourth loss in five games.

Lynn was left frustrated after giving up a game-tying hit to Blue Jays slugger Vladimir Guerrero Jr. on a 3-0 pitch with two outs and a runner at second in the sixth, right after the White Sox had opened the scoring.

"That was stupid," Lynn said. "There’s no other way to say it. I told Tony that when I got in, that was all on me. I was trying to throw a ball and it ran back over the plate. There was never an intention to throw a strike.

"You can’t let Vladdy beat you there on a 3-0 pitch, no matter what," Lynn added.

Seemingly upset at the 3-0 pitch, LaRussa was seen talking angrily with catcher Seby Zavala at the end of the inning. However, LaRussa didn’t want to discuss his reaction after the game.

"It’s one of those situations where it’s right out there in front and everyone can decide what the comment would be if I decided to comment, but I’m not going to comment," LaRussa said.

The Blue Jays, who came in having lost seven of nine, improved to 9-14 in one-run games.

Lynn allowed one run and four hits in seven innings, but didn’t figure in the decision for the fifth consecutive start. The right-hander has not won since a road victory at Milwaukee on July 25.

Lynn lowered his ERA to 2.20 and reached the innings threshold he needed to qualify as the AL leader in that category.

The White Sox opened the scoring with three straight singles off Blue Jays right-hander Alek Manoah in the sixth, including an RBI hit by outfielder Andrew Vaughn.

McGuire led off the bottom half with a double, but was thrown out trying to advance to third on Bichette’s grounder to second baseman Cèsar Hernández. Bichette advanced on a ground ball and scored on Guerrero’s single to center.

Manoah allowed one run and five hits in six innings.

The White Sox are 13-20 in one-run games.
