tough luck

Maybe Andy Roddick hasn't recovered as well as we all think from his loss at Wimbledon. Look at the losses he has had since then.

He lost two tight matches to Juan Martin del Potro, in Washington, D.C., and Montreal. I think the one in D.C. ended in a third-set tiebreak.

He lost to Sam Querrey in Cincinnati in two tiebreak sets and now to John Isner in a fifth-set tiebreak.

I get the feeling when things get close in the end, he just doesn't have the confidence to pull it out.

What do you think of his losses? -- Beth D., Brooklyn, N.Y.
