DENVER - Pinch-hitter Ryan Raburn came through with a go-ahead, two-run homer in the seventh inning that carried the Colorado Rockies past the New York Mets 4-3 on Sunday for a three-game sweep.

Tyler Chatwood (5-3) pitched seven solid innings and Carlos Gonzalez also homered for the Rockies, who swept the Mets for the first time since April 2013. Colorado has won four straight games and closer Jake McGee has earned a save in each one to increase his season total to 12.

Yoenis Cespedes homered but it wasn't enough for the Mets, who wasted a strong start by Jacob deGrom and finished 4-7 on their NL West road trip.

New York gave deGrom a 3-1 lead by scoring twice in the third. He allowed just three hits until Gonzalez went deep with two outs in the sixth. DJ LeMahieu led off the seventh with a 12-pitch walk against deGrom, who left one out later.

Jim Henderson (0-2) came on and Raburn hit a 2-2 pitch into the Rockies' bullpen.

That took away a potential win from deGrom, who yielded three runs and four hits in 6 1/3 innings.

New York tried to rally in the eighth, but Juan Lagares was called for running out of the baseline between second and third on Lucas Duda's roller to third baseman Nolan Arenado. Colorado was awarded a double play that ended the inning.

Chatwood earned his first win at Coors Field since April 18, 2014. The right-hander, who allowed three runs and six hits, missed most of that season and all of 2015 after undergoing Tommy John surgery.

TRAINER'S ROOM

Mets: Manager Terry Collins said he is waiting to make any decision about pitcher Steven Matz until after the lefty sees a doctor about his sore elbow. Matz missed his scheduled start Saturday but could be back for this week's series against Washington. "If they give him the OK, he could conceivably throw a little bit on Monday and pitch Thursday," Collins said. "We'll just wait to see. Until I get the report from the doctor, we're going to let it hang out there."

Rockies: LHP Tyler Matzek (anxiety) was scheduled to pitch Sunday for Class A Modesto. As planned, he faced one batter each Friday and Monday and walked both on four pitches.

NO PRESSURE

The Mets open a key three-game series against NL East-leading Washington on Tuesday at Citi Field. Collins said before Sunday's game that he is not putting too much emphasis on the first three of 19 games against the Nationals.

"Is it the biggest series of the year? It's yet to be determined," Collins said. "It's the big leagues. It's supposed to be like this. When you play another good team and it's in your division and you're playing for something important, it's always fun."

SLUMP BUSTER

Gonzalez ended a 98-bat homerless streak, the longest of his career. He had not gone deep since April 16 at the Cubs, a span of 24 games, and it was his first RBI in 18 games.

UP NEXT

Mets: RHP Noah Syndergaard (3-2, 2.53 ERA) gets the nod for the opener against Washington on Tuesday night. Syndergaard is 1-0 with a 1.80 ERA in three career starts against the Nationals.

Rockies: RHP Chad Bettis (3-2, 4.56) opens Colorado's nine-game, 10-day road trip when he faces the St. Louis Cardinals on Tuesday. It will be his first appearance at Busch Stadium.
