FLUSHING MEADOWS, NY—Former North Carolina High School Athletic Association tennis champion John Isner had his great run in the 2015 U.S. Open Tennis Championships ended in a tough match Monday night.

         Isner fell to the second-seeded player, the legendary Roger Federer, in three close sets by 7-6 (0), 7-6 (5) and 7-5, to advance to the tournament quarterfinals.

         One of the hardest serving players on tour and one of the biggest at six feet, 10 inches, Isner had serves clocked at a whopping 140 miles per hour during the night. Federer’s ability to return some of those booming serves was a key in the match.

         Isner won the 2001 NCHSAA 4-A men’s singles champion.
