NEW YORK— Their new home was gorgeous. The Mets looked lost.

Jody Gerut christened Citi Field with a leadoff homer, Adrian Gonzalez also connected and the San Diego Padres spoiled New York's first regular-season game in its glittering new ballpark with a 6-5 victory Monday night.

Pedro Feliciano balked in the go-ahead run and the Mets made several key mistakes, opening Citi Field the same way they closed Shea Stadium: with a dud.

David Wright rallied New York from an early four-run hole with a tying homer, but it wasn't enough. Padres relievers Duaner Sanchez and Heath Bell, both former Mets, closed out the fifth straight win for surprising San Diego (6-2), expected to be one of baseball's worst teams this year.
