Tennis players often use percentages to measure their performance. Unlike football managers, who talk of the “the lads giving 110%”, tennis is more realistic. Agassi, who has scotched any idea of retirement for now, was quoted at the Hall of Fame ceremony about missing Wimbledon and his hip problem:<br /><br />”the other option was to be in pain on the court, moving at 50 percent,” he said. “Between the clay and the grass, I was 30 percent the player that I expect myself to be.”<br /><br />From Agassi, you accept that analysis. But somehow, when it’s the Williams sisters, it’s more annoying. Serena got a lot of flak for saying she was only 20% during her Wimbledon run as she barely lost a game till the semi. And fair enough. It’s a bit disrespectful to the other players to win one-and-one and claim to be playing badly. And now Venus is in on the act. Quoted today in Reuters, she said: “I know that when it comes to the abilities I have, no one on tour can match that.”<br /><br />Really? I hardly think Venus is the best player on the tour. She’s not even the best player in her own family.
