Mets’ big bats struggle in loss to Rockies

DENVER — A change of scenery and altitude didn’t do much last night to invigorate the zombies inhabiting the Mets’ lineup.

The Mile Low Club — with Jason Bay and David Wright, among others, presiding — went into full session. The Mets never got anything resembling a clutch hit and lost their second straight, 2-1 to the Rockies at Coors Field.

They even had the potential tying run — Willie Harris, who had a pinch-hit single to lead off the ninth — thrown out trying to steal second for the inning’s second out.

The Mets began play batting a pathetic .223 with runners in scoring position and saw that number drop with an 0-for-7 performance last night. Five singles and six walks accounted for the Mets’ offensive output.

“Your main guys have got to hit,” manager Terry Collins said. “Your main guys have got to be the supplier of your offense, and we’ve got to get those guys going for sure.”

Bay, who has only one homer in 57 at-bats this season, might be the Mets’ top underachiever. He hit a rocket in last night’s eighth inning, but saw it land in center fielder Dexter Fowler’s glove, a few feet from the fence.

“I took early [batting practice] and regular BP and the ball was carrying pretty well,” Bay said. “It doesn’t carry as well, I guess, at 9 o’clock [MDT], which is kind of the way things are going for me right now.”

But Bay, who is batting .228, said he was encouraged by his at-bats.

“The process was there and everything felt good,” Bay said. “Now I kind of feel like I’m gaining momentum, rather than still waiting to find it. Although it would have been a lot nicer if that ball had gone out, you kind of take the positive from it, even though it really doesn’t help you sleep at night.”

Mets starter Chris Capuano allowed two earned runs on five hits and three walks over 6 2/3 innings, but still took his third consecutive loss. It was a second straight start in which Capuano (2-4) worked beyond six innings and allowed only two runs.

Capuano was pitching a gem into the seventh, when Chris Iannetta hammered a changeup that just cleared the left-field fence — a solo homer that gave the Rockies a 2-1 lead.

Capuano seemed most upset with the fact he struck out three times, including with the bases loaded in the sixth.

“I would like to do some little things to help myself out,” Capuano said. “Put the ball in play when there are runners on base and give myself a chance to at least help myself.”

The Mets didn’t break through against Jhoulys Chacin until the sixth inning, when Carlos Beltran scored from third on Bay’s chopper to make it 1-1.
