His strokes are similar to WTA player Pironkova and Andy Murray (with less power). He won't win matches in today's game... tennis now is all about power.
In a way it's sad that most if not all of today's strategy is based on power. It really makes most of today's tennis boring to watch for many, especially for the majority of the population with limited opportunity to appreciate the intricacies of shotmaking, except in the case of legends like Federer where artistry is up there with power for the lay person to appreciate. It's good that players like Mecir, Hingis, Hewitt, have graced the sport to show that smarts can win over brawn. I hope such era makes a comeback in tennis.
