Giants starting left tackle David Diehl was busted for DWI in Queens last night — with his blood-alcohol level allegedly more than twice the legal limit — after smashing into parked cars, police sources said.

Diehl, 31, a member of both of Big Blue’s recent Super Bowl teams, was driving his black BMW when he struck two vehicles on 35th Avenue near 31st Street in Astoria at around 8:20 p.m., the sources said.

Diehl, who had been celebrating a few blocks away at Scorpio’s on Broadway while watching a soccer match, allegedly blew a .18 on the Breathalyzer. The legal limit is .08. He was not hurt, and was being held at the 114th Precinct station house early today.

Diehl, whose relatives hail from Croatia, was watching Croatia defeat Ireland, 3-1, in the European Championships.

Diehl enthusiastically Tweeted “Goooooaaaaaallllllllllllllll!!!!!” twice during the afternoon contest.

A Giants spokesman said he was not aware of the arrest until informed by a Post reporter.

Diehl’s agent, Peter Schaffer, would say only that the offensive lineman is “one of . . . the classiest, most humblest New York Giants ever.”

Diehl, who has been with the team since being drafted in 2003, won the Wellington Mara NFL Man of the Year Award on May 22 at the annual Boys Hope Girls Hope Dinner at The Pierre hotel.

He also Tweeted earlier yesterday said that he was at a charity golf tournament at the Westchester Country Club.
