Kentucky's Eric Quigley and Brad Cox advanced to the doubles quarterfinals at the NCAA Singles and Doubles Championships at Athens, Ga.
Quigley and Cox, ranked 22nd in the nation, defeated sixth-ranked Dimitar Kutrovsky and Josh Zavala of Texas 6-3, 6-4 on Friday.
The win sends a UK doubles team to the NCAA quarterfinals for the first time since Richard Benson and Greg Van Emburgh reached the semifinals in 1987.
Quigley and Cox will play 19th-ranked Clay Donato and Stefan Hardy of North Carolina at 2:30 p.m. Saturday. Donato and Hardy defeated second-ranked Robert Farah and Steve Johnson of Southern California 2-6, 6-4, 6-1 on Friday.
"They gave their best performance of the year today," UK Coach Dennis Emery said. "Brad took a big step forward and showed a lot of mental toughness and we needed that in order to get the win."
Earlier in the day, Quigley lost his singles match to Marcel Thiemann of Mississippi 7-6 (7-4), 3-6, 6-2. It marked the second loss for Quigley in his previous 16 singles matches dating to early April. The other loss was against Thiemann, too, at the Southeastern Conference Championships.
Louisville's Austen Childs became the first player in school history to reach the singles quarterfinals when he defeated Baylor's Denes Lukacs 6-4, 6-4. Next up is No. 10 Kutrovsky of Texas on Saturday.
Childs, ranked 19th, avenged a 6-3, 6-2 loss earlier this season to Lukacs.
"Coach (Rex) Ecarma and I had a pretty good game plan today," Childs said. "We worked on keeping the ball high and mixing up my serves. I played very well and it worked."
