Yuki Bhambri has qualified for the main draw of the 50,000 U.S Dollar ATP Challenger tennis tournaments at Knoxville, United States. The seventh-seeded Indian teenager stunned top seeded South African Fritz Wolmarans in straight sets 6-4 6-2. The victory over the 348th ranked Protea enabled Yuki to grab one of the four main-draw spots at stake. The lanky Delhi player has drawn American Lestor Cook as his first round opponent. No other Indian is in the fray in the tournament. Yuki had qualified for the Charlottesville Challenger last week and reached the second round of the main event.
