Newport - Top seeds John Isner, Kei Nishikori and Milos Raonic all advanced to the second round of the $398 250 ATP Hall of Fame Championships on Tuesday while three other seeds were eliminated.
US top seed Isner edged Ukrainian qualifier Sergei Bubka 7-6 (7/3), 4-6, 6-3, to book a second-round match on the Newport grass against Frenchman Nicholas Mahut, his opponent in the longest match in tennis history.

Japanese second seed Nishikori ousted Dutchman Igor Sijsling 6-4, 6-4 to book a second-round match against Belgium's Olivier Rochus.
Canadian third seed Raonic rallied to outlast Australian Matthew Ebden 3-6, 6-3, 7-5. Raonic next meets German qualifier Benjamin Becker, who defeated rising Belgian star David Goffin 6-4, 6-3.
South African Izak Van Der Merwe defeated eighth seed Gilles Muller of Luxembourg 7-6 (7/5), 6-7 (3/7), 6-4, while Russian fifth seed Alex Bogomolov fell to American Sam Querrey 7-5, 7-6 (7/5) and American Tim Smyczek beat Uzbek fourth seed Denis Istomin 6-3, 6-3. - Sapa-AFP
