Hansel Robles gives up winning HR, Mets go 0-6 on homestand

Let’s go (away) Mets.

After Sunday’s 3-2 loss to the Rockies capped an 0-6 home stand, the Mets will look to regroup on the road against Cincinnati and Philadelphia.

Sweeps by the Braves and Rockies left the Mets 17-15 after their 11-1 start. Ian Desmond’s second home run of the game — an eighth-inning solo shot off Hansel Robles — broke a 2-2 tie. The Mets had a chance in the ninth, but pinch hitter Tomas Nido struck out looking with runners on first and second.

And perhaps it will get worse before it gets better. Before Sunday’s game, Jacob deGrom, who was thought to have recovered from a hyperextended right elbow, was removed from Monday’s scheduled start against the Reds. He will be replaced by P.J. Conlon, who was 1-2 with a 6.75 ERA for Triple-A Las Vegas. In his major-league debut, he is being asked to be the stopper.

The bad news continued into the game. The Mets scored two runs in the first inning — their first lead since the previous Sunday in San Diego — but lost Yoenis Cespedes with a right quadriceps injury. There was no word on his status for Monday’s game.

All of this might have prompted former Mets manager Terry Collins to issue one of his frequent DEFCON warnings when things went awry.

Not so with Mickey Callaway. “You know what?’’ the first-year manager said. “I don’t think it’s a surprise. I don’t think I’m concerned. It’s just part of the game.

“What I try to do as the manager is look at the way we’re playing. If I just worried about results all the time — and I understand the game’s all about winning games — we’re trying to win games every single day, but to win the most games you can in the season, you have to worry about other things than just the results that day, and I think we’re all trying to stay focused on that because we know in the end, that’s what’s really going to matter most.’’

The Mets gave Noah Syndergaard the early lead against Rockies starter Kyle Freeland on Asdrubal Cabrera’s RBI single and Todd Frazier’s sacrifice fly. But Rockies pitchers allowed only two hits the rest of the way.

Syndergaard gave up Desmond’s first homer in the second inning and walked home the tying run in the third — the first time he’s allowed a bases-loaded walk in his career. He gave up six hits and walked four in six innings. It constituted a quality start, but not by his standards.

“Keep on getting those mediocre starts out of the way so I can dominate in September, I guess,’’ he said. “But I have to get out of the habit of thinking too much out there. Thinking too much about mechanics, trying to miss bats as opposed to just going out there [waiting] for the catcher to put the finger down and executing that pitch.’’

Callaway said, “His tempo was real slow in between pitches. He just didn’t look comfortable out there. He battled through it and gave us six innings, two runs, which you can never complain about . . . I don’t think we’ve seen the best of Noah Syndergaard yet.’’

Callaway acknowledged that the offense needs correcting. “Recently it’s just lack of runs,’’ he said. “It seems like we get to a spot in our lineup and all of a sudden, wherever it is, once we get something going, it just stops.’’

That occurred in the ninth. After Wilmer Flores walked with one out and was replaced by pinch runner Jose Reyes, Jay Bruce struck out. Adrian Gonzalez had a pinch-hit single, but Nido (.147) batted for Robles and was no match for Adam Ottavino and his 0.47 ERA.

Notes & quotes: Slumping outfielder Michael Conforto pinch hit in the seventh and struck out on four pitches. He’s batting .184.
