Tim Mayotte was a former ATP world #7 player in the 1980s and arguably the best player to ever come out of the United States New England section. A winner of 12 career ATP singles titles and a semifinalist at 1982 Wimbledon and 1983 Australian Open, Mayotte discusses his thoughts on young American Ryan Harrison and what needs to be worked on to take his game to the next level...Question: What does Harrison need to do to take it to the next level and do you think he has the potential to reach the top 10? Mats Wilander said he thinks Harrison has the goods to be top 3 in the world.Tim Mayotte: "I think Ryan has some technical issues that he needs to address, before he becomes great, particularly his backhand side. He can be vulnerable I think to a counterpunching type of backhand. Ultimately, the best players are going to break it down. So I think if he can address, not only the stroke, but also the way he addresses the ball, otherwise I think on most surfaces he's not going to be able to exchange with players to get to a chance to be able to use his forehand."Question: You do sense he can become a great player though?Tim Mayotte: "I think he's got the competitiveness. He's got the ability to win and certainly the ability to compete in big situations. He's very comfortable in those kind of matches...he's got that confidence in himself. He's got good shot selection. He knows what he can and he can't do. So all those elements I think are great. It's a question of technical things and whether you know through his - I mean, obviously Roddick had a great career but there was that one big weakness with his backhand - it made it very difficult for him to stay in exchanges with the best players."Question: If you don't mind my asking, what do you think Harrison can actually do to change his backhand? Isn't he so set in his way by now?Tim Mayotte: "No, no. I think that's one of the great misconceptions about pros. Things are locked in place. I think we're all aware of how, for instance, Nadal significantly changed his serve two weeks before the U.S. Open two or three years ago and also got a much better serve. And serve is more complicated than the backhand. Or, obviously, Federer is now flattening out the ball when he has to. Those are significant changes. But great players do that. Lendl developed his topspin backhand as his career went on. And his second serve. Great players adjust to get better. So I think that's a big mistake to say.""But if you were to look at the lack of length and the lack of rotation in his backhand, it's not creating nearly the amount of racquet head speed that he's capable of. He's clearly a good athlete. And I don't think that would be that hard to fix. And integrating. It takes time but the actual technical improvements - for a kid that talented. He's only 19. I don't think it's that difficult. His serve is excellent. All these things are in place. But that I think he can change. If he makes those adjustments I think he could be top 10."Tim Mayotte won the NCAA singles title in 1981 while playing at Stanford. He played on the ATP Tour from 1981-1992, achieving a career won/loss record of 340-203, including 12 singles titles. Mayotte defeated Connors in the final at Queens Club in London and also won the silver medal at the 1988 Olympics. His best results in majors were semis at Wimbledon and Australia and quarters at U.S. Open. Today he coaches various players in New York.
