Having just watched the final of the OZ open、I couldn't help but wonder if I was witnessing another turning point in the game. Everyone mentions how the advances in strings and racquets have produced today's power game, but looking at Djokovic outlast (outrun? out-retrieve?) Nadal the other day, despite the 31 shot rallies at 110%, I wondered if he isn't taking the game in another dimension? Can the stroke-making genius of Federer keep up as is against the type of player who gets into the position for everything in time to get everything back with more than a casual slice? You can see why Federer's head drops when the rallies and matches get longer against these guys. Love Federer, but saw his days numbered in last weekends final. Is tennis turning a new corner??
