HOUSTON -- John Isner is starting to live up to expectations. Isner has soared to the No. 10 world ranking this year with victories over three of the top players in the world. He arrived at River Oaks Country Club on Tuesday to begin preparations for the U.S. mens clay court championship. "Id like to think Im a nightmare to play," Isner said. "I kind of take away their rhythm. Im going to hit a lot of winners and Im also going to make mistakes. Im trying to not let those bother me. Over the course of a match, Id like to think my style is going to win out." Isner beat No. 3 Roger Federer in the first round of Davis Cup play. He upset No. 1-ranked Novak Djokovic in the semifinals at the Indian Wells Masters, and upended then-No. 6 Jo-Wilfried Tsonga of France. "A lot of guys out here playing are rhythm players," Isner said. "They want to get into a groove over the course of a match and thats what I dont want to give them." Isners performance against France advanced the Americans to the Davis Cup semifinals against Spain. "Im a much more confident player," Isner said. "To be able to compete in this game you have to be confident and thats what I have on my side right now. I know it can come and go very easily, too. But right now Im very confident in my ability and I think Ive proved that throughout the course of 2012." Confidence was his ally against Djokovic. "I believed I could win," Isner said. "I enjoyed the moment. Id never beaten the No. 1 player in the world. I beat the No. 1 player in the world, who over the past 16 months has dominated the game." Beating Federer also was a big step forward for Isner, who started the year ranked No. 18. "That was a great win for me and I played it the right way," Isner said. "Thats when I realized thats how I have to play. Isners ascension has also created attention. "I can see why, I have played well so far this year," Isner said. "People have seen that when Im playing the right way and playing well, Im pretty tough to beat. Its up to me to be more consistent at that level and I know Im getting there. "I still think my best tennis is two or three years ahead of me." Isner faced high expectations coming out of the University of Georgia. "I wasnt ready for it then but now, I want people to expect a lot of me," Isner said. "Once you get up to top 10 in the world, people are going to expect a lot of you. I like it, I relish it. "I want to be that guy for American tennis. I dont want to be content to be No. 10 in the world. I want to keep on climbing." Isner is seeded second behind No. 9 ranked Mardy Fish and will play his first match on Thursday. wholesale jerseys free shipping .C. -- Steven Holcomb extended his season-opening winning streak to three titles in World Cup two-man bobsled racing Friday, beating Canadas Lyndon Rush by 0. wholesale jerseys .
