Marat Safin was fined the maximum $10,000 for refusing to attend a news conference after his first round defeat at the French Open on Tuesday, the International Tennis Federation said.
The Russian former world number one was beaten 6-3, 1-6, 6-3, 6-1 by ninth-seeded Chilean Fernando Gonzalez, his earliest defeat at Roland Garros.
It is the second time Safin has declined to attend a press conference at the French Open. He was also fined $10,000 for skipping one in 2001.
Safin, who missed last year's U.S. Open and this year's Australian Open with a knee injury, has slipped to 53rd in the rankings.
