Matt Harvey's golden arm has shown a little tarnish in recent starts.
Harvey (8-3, 2.21 ERA) has won just four of his last 18 starts after winning his first four this season. The right-hander has allowed three or more runs in three of his last five starts, including Thursday against the Miami Marlins, who reached him for three in 5 2-3 innings of the Mets' 3-0 loss.
"He deserves a better fate than what he has had," Mets manager Terry Collins said. "He has pitched great. We just don't score many runs."
Harvey has held left-handed batters to a .172 average, the second-best figure among right-handed starting pitchers. The Marlins' lefties, though, went 3 for 7 after Harvey had limited those hitters to 2 for 38 with 16 strikeouts his prior three starts.
"I only have one concentration, and that's my job at hand," Harvey said. "I'm going to say that until I'm blue in the face. My job is to put up zeros, and obviously I didn't do that today."
Harvey, who had eight strikeouts, leads the National League with 10.27 per nine innings.
He'll now face a Colorado squad that is 1-7 on its 10-game road trip. The Rockies (52-62), who opened their road swing with a 9-8 loss and 15 hits at Atlanta on July 29, have scored 14 runs and hit .223 since.
Troy Tulowitzki is 0 for 8 with four strikeouts in his last two games and 3 for 25 on this trip, while DJ LeMahieu is 2 for 16 his last four games.
New York's offense hasn't been much better, averaging 2.5 runs over its last 11 games. With just three home runs over that stretch, the Mets (50-60) have had to rely on small ball.
Eric Young has helped the Mets there, compiling 15 steals in 41 games since being acquired June 18 from Colorado, where he had eight in 57 contests. Young scored from second on an infield hit in the eighth to give the Mets a 3-2 victory over the Rockies on Tuesday night.
"He's got game-changing speed, and it got them a win tonight," Rockies manager Walt Weiss said.
Juan Lagares, who had the go-ahead single, has also brought additional speed to the lineup with three triples in his last seven games.
Mets first baseman Ike Davis is 7 for 12 with four doubles and a .737 on-base percentage over the last six games.
They'll face Colorado's best pitcher of late, as Jhoulys Chacin (10-5, 3.40) boasts a 7-2 record and a 2.24 ERA over his last 10 starts. That includes eight innings of one-run ball in a 4-2 victory over Pittsburgh on Friday.
"This year, we gave him the responsibility of being a top-of-the-rotation guy, and he's taken it and he's run with it," Weiss said.
Chacin has been dominant away from Coors Field, posting a 1.78 ERA in eight starts while allowing one home run.
Chacin has lasted deep into games, going at least seven innings in three straight starts. On Friday, he was able to push through eight despite being struck on the right forearm by a batted ball in the fifth inning.
Chacin is 1-0 with a 1.38 ERA in three lifetime starts versus the Mets, beating them Aug. 21 after limiting them to one run in six innings of a 6-2 win.
