Kolev, a senior who ended is two-year Arkansas career with a combined mark of 53-26, won his first-round match on Wednesday, beating Matt Klinger of Arizona State in a three-set tiebreaker, 3-6, 6-2, 7-6 (7-4).
"Oggie had a good season and a good career for us," head coach Robert Cox said. "He stepped into the No. 1 position this year and did a really good job of following Oskar Johansson and helping our team make another NCAA regional final. He played well in the NCAA Tournament. Mankad was just too tough. He was ranked No. 1 in the fall and is one of the best players in the country."
Mankad is seeded third in the tournament and is ranked fourth in the nation by the Intercollegiate Tennis Association. Kolev is ranked No. 35.
Earlier this week, Southern California, which eliminated Arkansas from the NCAA Tournament with a 4-0 regional final victory in Tulsa on May 11, won the national championship with a 4-1 win over defending national champion Georgia.
