NEWPORT, R.I. (AP) -- Top-seeded John Isner continued his strong run on Newport's grass courts Thursday, reaching the semifinals of the Hall of Fame Tennis Championships with a 7-6 (5), 6-4 win over No. 5 seeded Alex Bogomolov.
Isner had 21 aces -- four in the tiebreak and three in the final game -- while becoming the first top seed to gain the semis since Andy Murray in 2006.
The top-seeded player has never won the title in the tournament's 35 years.
Isner will face eighth-seeded Tobias Kamke, who beat Edouard Roger-Vasselin, 3-6, 6-1, 6-3, in the other quarterfinal Thursday.
They will play on center court Friday following an induction for the 2011 class. Andre Agassi headlines the class that will be enshrined during an on-court ceremony.
