New Port (Rhode Island):Indian qualifier Rohan Bopanna pulled off a sensational victory over top seed Mardy Fish 7-6 (8-6), 7-5 in the second round of Campbell's Hall of Fame Tennis Championships.
Bopanna, who turned professional six years ago, fired 14 aces and converted three of his four break points in beating the world 41 on Wednesday in the $385,000 event.
The 28-year-old will now meet compatriot Prakash Amritraj who beat another American, Jesse Levine, 7-5, 6-3 in his second round match.
Bopanna, ranked a lowly 374th on the ATP charts, has registered by far his best victory and that, too, on grass where he has a 7-19 win-loss record.
Bopanna, who had beaten American Kevin Kim in the first round, won two matches in a row for the first time on the circuit on his way to his first quarter-finals.
"I was not concerned about what ranking he was," Bopanna said. "I was aggressive and kept it simple."
"It is extremely disappointing," Fish said. "Every year I come in thinking I have the game and I am ready. Every year I leave here scratching my head."
Canadian seventh seed Frank Dancevic had to eke out a tough victory over American Brendan Evans 5-7, 6-4, 7-6 (7/3).
Dancevic, who had knocked out seventh seed David Nalbandian in the first round at Wimbledon, will play Russian Igor Kunitsyn who breezed past compatriot Mikhail Ledovskikh 6-1, 6-1.
