ADELAIDE, Australia(AP) John McEnroe has criticized the handling of tennis match-fixing claims, saying the suspension of Russia's Ekaterina Bychkova does not make sense.

Last week, the Tennis Integrity Unit fined Bychkova $5,000 and barred her from playing for 30 days. The anti-corruption unit accused Bychkova of failing to report that she was asked to provide inside information and throw matches.

McEnroe called match-fixing a ``huge concern'' for tennis, and said Bychkova had been suspended after turning down an illegal approach, which he believes might dissuade other players from being honest.
