A 225 kph serve, 2 meters and 6 tall, a big forehand. John Isner, the guy who came out of nowhere this summer to reach the final of the Legg Mason in Washington, could be a serious test for world n.1 Roger Federer in the US Open third round. He gives his opponent no rythm, has great support from the crowd. He could get fired up and play the match of his life in front of the three-time defending champion.

By his physical features and style of play, Isner reminds me of Marc-Kevin Goellner, a German player of the 90’s who claimed some good results against top-players. For example, he beat Stefan Edberg and Ivan Lendl back to back in Nice in 1993. He also won Davis Cup with Germany that same year.

Roger doesn’t seem to suffer big servers (given his outstanding record against Roddick), but that third round could be a match to see.
