'I can tell it's going to be in when it leaves my racket' — Kim Clijsters

During today's post-opening match press conference, she was asked about a challenge she made during the match (the first one she's ever made at the U.S. Open, what with her absence from the tour over the past 18 months to have a child).

She responded (up top in the headline — as close as I can recall to her actual words) that she challenged the line call (it was overturned and her challenge upheld, with the shot hitting about one millimeter of chalk) because of how good the shot felt leaving her racket.

That's an example of the enormous difference between players on her level and the rest of us: it's enough for me that it just leaves the racket.
