PHOENIX (AP) — The New York Mets are struggling out West, no one more than Mike Pelfry.

The right-hander lasted just 1 1-3 innings in the shortest outing of his career and the Arizona Diamondbacks went on to rout the Mets 13-2 on Monday night.

Mark Reynolds led the Diamondbacks’ barrage with an RBI triple and three-run homer, his 21st of the season.

Mets manager Jerry Manuel said Pelfrey needs to go back to the fastball that got him off to a 9-1 start. In his last six starts, Pelfrey is 1-4 with a 9.11 ERA.
