The ATP is looking into reports of possible match-rigging, but the head of the men's tour, Mark Miles, doesn't believe any players are involved.

The ATP chief executive was responding to a report in a British newspaper alleging possible match-rigging.

The ATP got permission from the online gambling company Betfair to see its clients' records, part of an effort to make sure players aren't involved in fixing matches.

Last week, bookmakers reportedly suspended betting six hours before a match in Lyon, France, between Yevgeny Kafelnikov and Fernando Vicente after a big wager was placed on Vicente, winless since June.

Vicente won in straight sets. There was no suggestion that either player was involved in any wrongdoing.

"To read what you guys are writing, that I have been involved in match-fixing in men's tennis, is definitely hurting my feelings," Kafelnikov said after withdrawing from his first-round match at the Madrid Masters with sore left foot.

"All I can tell you is that tennis players have never been involved in match-fixing. We are playing for our living."

He lost the first set 6-3 to Thomas Enqvist before quitting Tuesday's match.
