An intervarsity tennis game at Ohio State University in Columbus between two old high school rivals turned ugly for a moment on Friday, February 9, as one player spit on his hand before attempting to shake his opponent’s.

Texas A&M freshman Patrick Kypson faced off against former high-school rival and current Ohio State freshman JJ Wolf at Ohio’s State Varsity Tennis Center. Wolf defeated Kypson 3-6, 6-3, 6-4.

After the game ended, Wolf approached the net to shake Kypson’s hand, only for Kypson to spit on his hand before reaching out to Wolf.

A clip shared to Twitter by Ohio State University student Rohith Koneru shows Wolf spotting Kypson’s spit and moving his hand out of the way.
