BUFFALO, N.Y. -- Lourdes Gurriel Jr. hit a home run completely out of Sahlen Field and Hyun Jin Ryu made the early lead stand up, winning his fourth straight decision as the Toronto Blue Jays beat the New York Mets 7-3 Sunday.
Santiago Espinal hit a three-run double in a five-run sixth inning as the Blue Jays remained a half-game ahead of the New York Yankees for second place in the AL East. Toronto is 3 1/2 games behind Tampa Bay for the division lead.
The Blue Jays won the final two games of their series against the Mets after getting routed 18-1 in Friday night's opener. New York dropped five games below .500 and remains out of the NL playoff field.
Colorado, Milwaukee, and Cincinnati are all ahead of the Mets in the postseason race.
"That's the toughest part, knowing that we have to win and other pieces of the puzzle have to fall into place," New York's Todd Frazier said.
Pitching on an extra day's rest, Ryu (4-1) allowed one run and eight hits in six innings, struck out seven and walked none.
"The extra day helped," Ryu said through a translator. "I felt fresh. Today I felt good on the mound."
The left-hander retired his final eight batters, fanning four. Ryu has not lost since July 30 against Washington, his second start of the season.
"He's an ace," Blue Jays manager Charlie Montoyo said. "Early on, phew, they were on to him, and then he made an adjustment and did a great job."
Gurriel made a sliding catch in left in the first, then connected on the first pitch he saw in the second. His 447-foot drive left the Triple-A ballpark the Blue Jays are using as their temporary home, clearing the high screen in left that's intended to keep balls from landing on neighboring Oak Street.
"Every time he goes to hit, I think he's going to hit a homer," Espinal said of Gurriel. "It's been fun to watch."
New York's Dominic Smith hit a two-out RBI single off Ryu in the first but the inning ended when Frazier got caught in a rundown between third and home.
"Those types of events happening are just going to challenge us, especially at this point of the season," Mets manager Luis Rojas said. "We have 13 games to go, we've got to clean it up."
New York's David Peterson (4-2) lost for the first time since Aug. 2, allowing two runs and three hits in five innings.
"I just pretty much stunk," Brach said. "There's no other way to really explain it."
Mets: New York activated LHP Steven Matz (shoulder) off the injured list and optioned RHP Drew Smith to the alternate training site. Rojas said Matz was available out of the bullpen against Toronto. . Brandon Nimmo started in center in place of Jake Marisnick, who is day-to-day after leaving Saturday's game because of a tight right hamstring.
Blue Jays: OF Teoscar Hernandez (strained left oblique) took swings on the field before the game. . RHP Nate Pearson (elbow) and RHP Matt Shoemaker (shoulder) are both expected to throw live batting practice later this week, manager Charlie Montoyo said.
Mets: New York is off Monday. RHP Rick Porcello (1-4, 6.07) starts Tuesday in the opener of a three-game series at Philadelphia. The Phillies have not named a starter.
