STONE MOUNTAIN, Ga. — After winning his first five matches of the tournament, Arkansas’ Oggie Kolev was eliminated from the Intercollegiate Tennis Association All-American Championship on Tuesday, but the doubles team of Kolev and Aleksey Bubis filled in and advanced. Kolev, who won his first eight matches of the year, lost to Mike Kosta of Illinois, 6-2, 7-5, after earlier recording wins over Peter Shults of Duke, 6-2, 6-3; Sean Monk of Tulsa, 6-2, 6-2; Royce Ramey of Texas Tech, 6-3, 6-3; Nicholas Monroe of North Carolina, 6-3, 6-1; and David Lowenthal of Wake Forest, 4-6, 6-1, 6-2. “He didn’t play his best, he was a little flat,” head coach Robert Cox says. “It’s kind of a downer for him to finish that way, but he’s got another chance in doubles. He started the year 3-0 and then ran off five wins here. That’s a good start to a good senior season.” In doubles, Kolev and Bubis, who went 2-1 in the singles tournament, won their first two matches before losing to Alabama’s Ryan Gostik and Stephen Mitchell, 8-6. When a team from Stanford dropped out of the tournament, Kolev and Bubis were asked to fill in. They responded by beating Vince Baudat and Julien Gillet of South Alabama, 8-5. They play again on Wednesday, needing a victory to reach the main draw of the tournament.
