DENVER — Steven Matz doesn't regret the 401-foot home run by Trevor Story. The juicy sinker to pitcher Antonio Senzatela will stick with him.

"I got ahead of him and I made a really bad pitch," Matz said. "That's what it boils down to."

Senzatela hit a tying, two-run single that ended a year-long 0-for-44 slide at the plate, and Story followed three pitches later with a three-run homer to cap a six-run fourth inning. The Colorado Rockies beat the Mets 9-4 Monday night to drop New York five games back for the second NL wild card with 12 games to play.

"We can't really think about that too much," Matz said. "We've been in a hole in the season before, and we've got to go and play our best baseball and let the standings take care of themselves."

Brandon Nimmo, batting leadoff for the first time since May 17, opened the game with a home run off Senzatela (10-10). Starting their last road trip of the regular season, the Mets built a 4-1 lead on Jeff McNeil's two-run homer in the third that stopped an 0-for-13 slump and Amed Rosario's RBI double in the fourth.

Matz, who allowed Ian Desmond's second-inning homer, needed 42 pitches to get through the fourth and dropped to 0-2 with a 10.15 ERA in three starts at Coors Field.

Charlie Blackmon singled with one out, Ryan McMahon walked and Garrett Hampson hit an RBI single with two outs.

No. 8 hitter Drew Butera walked to bring up Senzatela, who had not gotten a hit since a two-run single off San Francisco's Dereck Rodriguez on Sept. 16 last year. With the count 1-2, Senzatela lined a sinker into left field.

"Just looking for something to hit, get a base hit," Senzatela said.

Story followed with a drive into the left-field seats off Matz (10-9), who allowed seven runs, six hits and two walks in four innings.

"A pitch out over the plate and he got a base hit," Mets manager Mickey Callaway said. "That kind of opened up the floodgates.

Senzatela gave up four runs and eight hits in six innings.

"I felt really good with the breaking ball today," he said.

Desmond made a nice leaping catch near the top of the left-field wall against Nimmo in the fifth.

Hampson had three hits, including a run-scoring single in the seventh off Paul Sewald, and Nolan Arenado hit an RBI double in the eighth against Edwin Díaz.

Mets rookie Pete Alonso ended a career-worst 0-for-21 slump with a fourth-inning single.

TRAINER'S ROOM

Mets: RHP Robert Gsellman (right tricep tightness) could return before the end of the regular season, Callaway said. ... Callaway said INF Dominic Smith (right shoulder) is in Florida and will begin baseball activities soon.

Rockies: LHP Kyle Freeland (left groin strain) is scheduled to throw a simulated game on Tuesday. Freeland, out since Aug. 21, hopes to return this season.

HOMER HAPPY

Colorado has allowed 16 leadoff homers, tying the major league record set by the 2017 Seattle Mariners, according to the Elias Sports Bureau.

HITTING THE WALL

Mets LF J.D. Davis ran into the wall after snaring Story's drive in the eighth inning. He lay on the ground and was looked at by a trainer but stayed in the game.

Davis was surprised to see Alonso run over from first base to check on him.

I asked him, 'What are you doing out here?'" Davis said. "And he said, 'I've got to check out the Sun Bear.' I said, 'You're ridiculous, go back to first.' Sun Bear, I guess that's his new nickname for me."

UP NEXT

New York RHP Marcus Stroman (8-13, 3.35), making his ninth start since joining the Mets on July 28, will face Colorado RHP Tim Melville (2-2, 5.16) Tuesday night.
