Austin Wells snapped a tie game with a three-run homer in the seventh inning as the New York Yankees rallied for a 10-4 victory over the Kansas City Royals on Monday that extended their lead atop the American League East.

The Yankees scored seven times over the seventh and eighth innings to erase a 4-3 deficit and take the opener of this three-game series between AL post-season contenders.

New York also received some assistance from its biggest rival, as the Boston Red Sox rolled to a 12-3 win over Baltimore that increased the Yankees' advantage over the second-place Orioles to 1 1/2 games in the division race.

Wells added a run-scoring double and Alex Verdugo had a two-run homer among his two hits for New York. Gleyber Torres and Aaron Judge also knocked in runs in the win, with Torres ending 3 for 5 and Judge collecting two hits. 

Salvador Perez went 4 for 4 with a home run and three RBIs for Kansas City, which currently holds the AL's second wild card. The Royals also received a solo homer from Hunter Renfroe, but had a four-game winning streak snapped after failing to protect a one-run lead in the seventh inning. 

James McArthur (5-7) entered with one out in the bottom of the seventh and allowed a single to Torres before walking Juan Soto in front of Judge, who ripped a single to left to bring in Torres and tie the game at 4-4.

Wells followed with a blast deep into the seats in right center field to put New York ahead.

The Yankees tacked on three more runs in the eighth. Oswaldo Cabrera doubled and later scored on a Torres single, and New York loaded the bases with none out before Judge hit into a double play to bring in another run. Wells then delivered a double that plated Anthony Volpe for a 10-4 advantage.

Verdugo's two-run homer off Brady Singer in the fourth inning gave the Yankees a 3-2 lead, though the Royals pulled even in the fifth when Bobby Witt Jr. reached on a single and scored all the way from first on Perez's blooper to right that fell in for a hit.

Kansas City went ahead an inning later on Renfroe's homer off Carlos Rodon, who struck out nine in six innings but permitted four runs - three earned.

Perez singled in a run in the first inning and homered in the third to put Kansas City up 2-0, but the Yankees later countered with three runs in the fourth.

Jasson Dominguez, called up from the minors before the game, singled in the fourth and eventually scored on Perez's throwing error as the young Yankee outfielder stole third base. Verdugo followed with his 12th homer of the season for a 3-2 New York edge.

Mets rally late to down Blue Jays, boost play-off hopes

New York's other team also improved its play-off standing, as the red-hot Mets scored twice in the eighth inning to pull out a 3-2 win over the Toronto Blue Jays.

The Mets got their late runs on a wild pitch and a passed ball to win for the 10th time in 11 games and move one game clear of Atlanta in the race for the National League's third and final wild card spot. The Braves were handed a 1-0 loss by the Cincinnati Reds on Monday.

Tyrone Taylor scored the tying run after pinch-running for Jesse Winker, who drew a lead-off walk against Tommy Nance in the eighth with the Blue Jays ahead 2-1. Toronto third baseman Ernie Clement's throwing error on an infield single hit by Francisco Alvarez allowed Taylor to reach third, and Taylor scored when Nance uncorked an errant pitch.

Alvarez moved to third on the play, then crossed the plate when Blue Jays catcher Brian Serven couldn't handle Nance's pitch for a passed ball.

Relievers Ryne Stanek and Edwin Diaz held Toronto scoreless over the final two innings, with Stanek recording the win and Diaz working the ninth for his 17th save.

Mets starter Tylor Megill left with a no-decision despite yielding just one hit and striking out nine over six scoreless innings, as the Blue Jays scored twice off New York's bullpen in the seventh to erase a 1-0 deficit.

Toronto loaded the bases with one out on a hit batter and singles by Clement and Alejandro Kirk. Jose Butto then hit Leo Jimenez with a pitch to force in the tying run, and Nathan Lukes followed with a sacrifice fly to put the Jays ahead.

The Mets had taken a 1-0 lead in the fourth. After Pete Alonso walked and Jose Iglesias was hit by a pitch, J.D. Martinez delivered a single to right to score Alonso from second.

Cantillo's gem lifts AL Central-leading Guardians over White Sox

Joey Cantillo took a perfect game into the seventh inning en route to his first major league win as the Cleveland Guardians held on for a 5-3 victory over the lowly Chicago White Sox.

Cantillo (1-3) retired the first 20 Chicago hitters before Andrew Benintendi singled with two outs in the seventh. The rookie left-hander surrendered a run-scoring single to Andrew Vaughn after that before completing his superb seven-inning stint with 10 strikeouts.

David Fry and Bo Naylor supported Cantillo with solo homers as Cleveland increased its lead in the AL Central to 3 1/2 games over second-place Kansas City. The Guardians also remained a game back of the New York Yankees for the AL's best record.

Chicago, meanwhile, set a franchise record with its 13th straight home loss. The White Sox fell to 33-112 overall and remained on pace for the most losses in a season in modern MLB history, set by the 1962 New York Mets (120).

The Guardians quickly jumped out to an early lead when Steven Kwan opened the game with a single, stole second, and scored on a base hit from Josh Naylor, who was then brought in by Lane Thomas' double for a 2-0 advantage.

Fry's homer in the third and Bo Naylor's blast in the fourth extended the margin to 4-0. The Guardians then tacked on another run in the fifth despite not recording a hit during the inning.

After Cleveland loaded the bases on two walks and an error, Chicago's Jairo Iriarte forced in a run by issuing a free pass to Jhonkensy Noel.

Benintendi stole second after breaking up Cantillo's perfect game bid before Vaughn drove him in with a single to get the White Sox on the board in the seventh.

Chicago got closer in the eighth on Bryan Ramos' first major league homer, a two-run shot off Nick Sandlin that followed Lenyn Sosa's single.

The White Sox did not get a hit the rest of the way, however, as Cleveland closer Emmanuel Clase struck out two during a scoreless ninth to record his AL-leading 43rd save.
