Bryce Harper played the ultimate teammate for a New Jersey high school student who just randomly walked up and Thurston Carteknocked on his door one day with a crazy plan in mind.

Jake Portello, a senior at Haddonfield Memorial High School, was looking for a little help getting a date to prom − so he wondered if Harper would deliver the pitch.

To Jake's amazement, the Phillies first baseman agreed.

"He seemed cool with it at first, then he was like, ‘Can I get your email so we can plan this out?’ and as I was leaving he was like, ‘Why don’t we do this right now?'" Jake told The Phantastic Sports Show on Monday night. 

And as usual, Harper came through in the clutch.

The video of the two knocking on the door of potential prom date Giulia's house went viral as she overcame her initial astonishment to accept the offer − with hugs for Harper first, and then Jake.

"I wasn't expecting this, I thought it'd be something cool among my friends and people in my town and stuff," Jake said. "I didn't even expect [Harper] to open the door in the first place."

Harper has already won two National League MVP awards, but after his latest assist, a certain New Jersey teenager would definitely advocate giving him another one.
