Ohio State keeps finding ways to thread the needle to victory in the NCAA men’s tennis championships.

Hugo Di Feo at No. 3 singles rallied over Texas Christian’s Guillermo Nunez 4-6, 6-3, 6-4 in the final match to give the Buckeyes a 4-3 quarterfinal victory Saturday afternoon in Athens, Georgia.

Di Feo fell behind after a service break in the third set. He pulled even at 4-4 with a winner on deuce point. (College tennis uses no-ad scoring.) But he fell behind 40-0 on his ensuing service game, only to win the next four points to stay on serve.

Di Feo then won three of the first four points on Nunez’s serve. Nunez saved one match point but hit a forehand wide on a let cord on the next point to give the Buckeyes the victory.

On Friday in its third-round match, Ohio State freshman JJ Wolf pulled out a dramatic victory at No. 2 singles against Oklahoma to give the Buckeyes a 4-3 win.

Wolf lost in straight sets today, and the Buckeyes found themselves tied when Mikael Torpegaard and Martin Joyce lost in three sets. Torpegaard fell to Cameron Norrie 5-7, 6-4, 6-3 at No. 1. Joyce lost to 6-3, 3-6, 6-2 at No. 4.

The Buckeyes won the doubles point when Torpegaard and Herkko Pollanen prevailed 8-6 in a tiebreak after Ohio State and TCU split the other two doubles matches. Pollanen at No. 5 won 6-4, 6-4 and Kyle Seelig at No. 6 won 6-3, 5-7, 6-3.

The third-seeded Buckeyes will play second-seeded Virginia in the semifinals on Monday.
