An excerpt from a post match article from today: He’s the first Russian man to reach the Key Biscayne final, and he’s seeking his first tournament title this year. He said he’s playing well because he changed rackets before the event, and has used the same racket in all five rounds. “It has a little bit more string, and I have more control,” he said. I checked a picture from the match today, and it was an 18x20 pattern. Looks like a switch to the Ozone Pro Tour to me, and he is sure playing well with the frame. With his aggressive, flat hitting style, I can see why a tighter pattern suits him.
