"Vomitgate" belched to its conclusion yesterday when Matthew "Pukemon" Clemmens pleaded guilty to throwing up on Phillies fans during an April game at Citizens Bank Park.

Clemmens primarily spewed upon an Easton police officer and his 11-year-old daughter, a fact that drew national headlines and - fair or not - more bad reviews for Philadelphia sports fans.

Clemmens, 21, of Cherry Hill, pleaded guilty to simple assault, disorderly conduct and harassment during a hearing at Philadelphia Family Court.

In exchange for the plea, the District Attorney's Office dropped other charges, including recklessly endangering another person, stalking and corruption of minors.

Clemmens will be sentenced in July.

Online court records indicate that he had no prior contact with the criminal-justice system in Pennsylvania, which likely will net him a sentence of probation.

Dave Clemmens, 48, the defendant's uncle, yesterday said he would not comment on the case until after his nephew is sentenced.

Following Matthew Clemmens' April 14 arrest at the ballpark, his uncle told the Daily News:

"The kid is one of the average kids who went to the game and had a few beers, and maybe a few beers before the game . . . Matt's a nice kid. Maybe a little overweight, but he has a good heart."

Police said Clemmens and a friend had been harassing Easton police Capt. Michael Vangelo and his 11- and 15-year-old daughters, which resulted in his friend's being kicked out of the stadium.

At that point, Vangelo told the Daily News, Clemmens announced his intent to vomit, stuck his fingers down his throat and spewed on Vangelo and the younger girl.

Clemmens kept barfing, police said, as he fought with disgusted nearby fans and as he was being taken into custody.
