Even a prodigious home run by Ike Davis and a spotless outing by Jonathon Niese couldn’t prevent them from looking silly in those skimpy soccer outfits Sunday.

Davis hit one of three New York homers, Niese won his fourth straight decision and the Mets put on an impressive power show at cavernous Citi Field in a 6-0 victory over the Minnesota Twins.

After the game, though, things got ugly.

As part of a baseball hazing ritual, the Mets dressed their rookies in Team USA World Cup uniforms for their trip to Puerto Rico to play the Florida Marlins this week. Tight-fitting navy blue jerseys, cut off haphazardly at the stomach, some with holes in ’em.

High white socks, short-shorts, mini soccer balls for props.

“Ike doesn’t look too good,” catcher Rod Barajas said.

“None of ’em look any good,” David Wright chimed in. Wright and Jeff Francoeur each hit a two-run shot before Davis went deep — very, very deep. New York racked up 14 hits and took two of three in an interleague series between playoff contenders, improving to 3-8 in rubber games this season. Francoeur finished a triple shy of the cycle, emphatically ending a 3-for-22 slide. Wright and Jesus Feliciano also had three hits as the Mets completed interleague play with a 13-5 mark, their most victories against AL clubs in one year.
