DENVER — The Mets are not going to get any breaks. Their long road trip included an injury to a starter, their bats cooling off, four straight losses and two bad calls. On Sunday, the Rockies rallied in the seventh and completed the three-game sweep of the Mets with a 4-3 win at Coors Field.  “No I am not frustrated. I am not happy, but it’s a part of baseball,” said Yoenis Cespedes, who hit his 12th home run Sunday. “You have to understand that things are going to happen on the road.”  Jim Henderson came in with a runner on in the seventh and gave up a pinch-hit, two-run homer to Ryan Raburn and the Mets’ chance to rally in the eighth was cut short by another questionable call.  After Juan Lagares doubled with one out and the Rockies intentionally walked Cespedes, Lucas Duda hit a roller to third and was thrown out at first. Third base umpire Carlos Torres called Lagares safe at third on the play because he avoided the tag attempt by Nolan Arenado, but second base umpire Rob Drake called Lagares out for leaving the base path to avoid the tag.  “I was surprised because the (umpire) in front of me said I was safe,” Lagares said. “The guy in back says out. No idea what happened. I never think I was going to be out.”  Terry Collins, who had been ejected by Torres for arguing a phantom foul tip call on Saturday, argued briefly with Drake, but the non-reviewable call stood.  “They made the call, it doesn’t matter. What’s it going to do? You don’t challenge it, so it’s over,” a clearly frustrated Collins said. “Let’s go. Move on.”  That is about the best thing the Mets (21-16) got out of Sunday: they can now go home. They have lost four straight games and were swept for the first time this season. The Rockies (19-18) swept them for the first time since 2013. The Mets come home in third place in the NL East, having fallen behind the surprising Phillies on Saturday night with the division-leading rival Nationals coming into Citi Field on Tuesday.  “It was a long trip with a terrible finish to it,” Collins said. “We’ll pick up the pieces; we have a long, long, long way to go. (Monday’s off day) will be a good rest day for us. We’ll get after it on Tuesday.”  The Mets have plenty to pick up. Their starting pitching, the cornerstone of this team, has struggled. Steven Matz is waiting to see a doctor Monday about his sore elbow. Matt Harvey said he was still searching for “a lot of unknowns” and Jacob deGrom is still fighting his mechanics and working without the velocity he had last season.  Sunday, deGrom got through 6.1 innings, allowing three runs on four hits, including Carlos Gonzalez’s home run in the sixth. He struck out three and walked three. That included walking DJ LeMahieu in the seventh, setting up Raburn’s homer.  “When I go out there, I go out there with what I got. You can’t think about it too much. You go with what you got and you do what you can with it,” deGrom said. “Kinda like I did today. My secondary pitches weren’t great, but I was getting hard-hit balls right at people. Got fortunate here. Go out with what you’ve got and work with that.”  The Mets’ bats cooled off considerably on this trip. They scored 32 runs over the 11 games and hit just .212. Sunday, Cespedes hit his first home run in a week and Michael Conforto showed signs of coming out of his funk with an RBI single in the Mets’ two-run third.  “We’ve got to bounce back and we will,” Collins said. “Actually the first part of this road trip we played pretty good. We came in here and with the team we have you think you are going to put some runs on the board and when you don’t do it you got to figure you are going to be in trouble here.”
The only good thing the Mets will be able to say about this road trip is that it is over.
