Lucas Duda may have been a victim of the cold at Coors Field.

The Mets left fielder departed Game 2 of Tuesday night’s doubleheader with tightness in his lower back, and will be evaluated on a daily basis. Mike Baxter replaced him in left field last night.

“It’s not a big deal, it kind of tightened up,” Duda said after the Mets’ 9-8 loss in Game 2 that gave Colorado a doubleheader sweep. “I should be in there [today].”

Duda said he first felt something in the back during his first at-bat in Game 2. He remained in the game to take two more at-bats before exiting.

* Aaron Laffey will start on three days’ rest Saturday against the Nationals if the Mets play the final two games of this series against the Rockies. Manager Terry Collins said he removed Laffey after four innings and 77 pitches in Game 2 to preserve him for Saturday.

Jeremy Hefner and Jon Niese are the scheduled pitchers for the final two games against the Rockies. Matt Harvey remains slotted for Friday against Stephen Strasburg and the Nationals.
