Tsyrenov, an All-SEC player who is ranked 27th nationally in men's singles play with a 13-12 record, rallied to take a 3-6, 6-1, 6-3 victory over Borja Sarco of Tennessee. On Thursday, in the round of 32, he will face seventh seed Lars Poerschke of Baylor.
Tysyrenov said, "I could not get used to the way he was playing in the first set--I was going for it too much, but I made some adjustments before the second set, thought about it a little bit and was able to come back."
Doubles play starts on Thursday as Elizabeth Ferris and Emily Kwok of Utah go against the Auburn duo of Alex Haney and Melissa Koning.
AU women's coach Tim Gray said, "Today was a good day for Fani. She was extremely focused and played very smart. We hope to see Alex and Melissa follow suit in doubles tomorrow."
