Three of the top men's tennis players in the world were assessed substantial fines on Thursday for failing to play in the required number of tournaments.

Stefan Edberg, the current No. 1, said he will appeal his fine which will be a minimum of $115,496.Also fined were No. 3 Ivan Lendl, who was set back at least $95,443 and fifth-ranked Andre Agassi, who was fined a minimum of $85,042.

The ATP said the amount of the fines would increase proportionally to include any income the players earn the rest of the year.

"It's quite a lot of money and I'll certainly appeal, probably early next year," Edberg said Thursday after winning his third-round match at the Stockholm Open.

Agassi, who was eliminated in the second round here on Wednesday by Swede Nicklas Kulti, was unavailable for comment. He left Stockholm early Thursday, according to an ATP spokeswoman.

Edberg and Agassi were required to play in 11 tournaments this year and Lendl one less because he is a 10-year-veteran.

All three are currently two tournaments short and the Paris tournament next week, in which they all are scheduled to play, is the final event before the season-ending ATP Tour World Championship at Frankfurt, Germany, from Nov. 13-18.

ATP Tour rules require a player be fined 10 percent of his income for each tournament he misses.
