Now, this is straight-up unfair!!

A D1 college softball star used her talents in a dunk tank challenge against her boyfriend … and guess what happened??

Yep — SPLAAAASH!!!

University of Illinois sophomore pitcher Addy Jarvis and Noah Drudy were partying with family members in Ohio over the holiday weekend … when Drudy decided to test his dry fate by hopping in the tank against the ace.

Of course, to try from a close distance would be WAY too easy for the Illini’s 2020 wins leader … so Jarvis tried it out from long range.

But, that didn’t help Drudy’s chances one bit … ’cause Jarvis wound up for the pitch … and nailed the target right on the nose!!!

Of course, it shouldn’t come as a surprise … Jarvis is a beast on the field … and even threw a one-hitter this season.

Better luck next time, Noah.
