Two frisky fans hit an inside-the-park home run in a Yankee Stadium bathroom as the Bronx Bombers beat the Tampa Bay Rays Saturday.

In a video posted on the sports blog Deadspin, fans can be seen watching as a man clad only in a hiked-up CC Sabathia T-shirt and a woman had full-on sex in the stall under the left field bleachers.

A tipster told the blog that the raunchy romp began in the second inning with the Yanks leading 3-0, and continued until the fourth or fifth — giving new meaning to the phrase pitching inside.

“People were jockeying for position outside the stall to take pics either over or under, and even standing up on the toilet bowl on the neighboring stall,” the tipster said.

Several stadium employees were among the slew of onlookers who flocked to the cinderblock bathroom, which bears a sign pledging “the highest possible levels of comfort with regards to quality and cleanliness.”

Fans “thought it was amusing that they should probably be using one of those walkie-talkies to call someone to do something about it (but) no one wants to blow the whistle on something as epic as this!!!” the tipster posted.

The couple appeared oblivious to the commotion around them, and allegedly continued to run the bases even after several onlookers cried foul.

Even after someone knocked on the stall door, the couple kept on copulating.

But eventually, the extra innings ended — and fans gave the woman a slow round of rhythmic applause as she parted.

The Yankees said Sunday that the team was aware of the situation but had no comment.

But the viral video was the talk of the Bronx after the Yanks’ 6—4 win Sunday, with some fans suggesting that baseball is not really the national pastime.

“Without a doubt, I would do that if you could get away with it,” said Joe Kocsis, 44, adding that it was wrong for people to videotape the duo.

The bathroom tryst struck out with others, who said they would never use a bathroom at the Stadium again.

“I would not sit on the seat after that,” said Victoria Wanderman, 33. “It’s definitely unsanitary, whether or not they’re using a condom.”

Vaze Morozoff, 49, agreed that the Yankee panky was “absolutely inappropriate.”

“This is a family environment, you have to be cool,” said the die-hard Bombers buff.

Stadium shenanigans aren’t, of course, limited to the Bronx.

A couple was arrested in 2008 for having sex in a woman’s bathroom while the New York Jets battled the Bills in Buffalo.

That same year, an Iowa woman was caught going at it in the bathroom at a Hawkeye football game in Minneapolis. In that case, her football-loving husband remained in the stands watching the game.
