Second-seeded Ivo Karlovic of Croatia used his overpowering serve to beat American Robby Ginepri 7-6 (2), 6-2 Monday in the opening round of the Hall of Fame Tennis Championships.
The 6-foot-11 Karlovic had 17 aces and only two double-faults, winning 92 percent of his first-serve points during breezy conditions on the grass at Newport.
The tournament is held in conjunction with the International Tennis Hall of Fame induction ceremonies. On Saturday, Lindsay Davenport heads a class that includes coach Nick Bollettieri, executive Jane Brown Grimes and broadcaster John Barrett in the contributor category and five-time Paralympic medalist Chantal Vandierendonck.
The Hall of Fame Championships is the only tournament in North America held on grass courts.
