Adolfo Daniel Vallejo has been fined half his French Open prize money after he said his second-round match should not have been umpired by a woman.
Vallejo lost to French teenager Moise Kouame last week after a tense five-set battle that lasted nearly five hours. He later told the tennis website Clay that "this sort of match needs to be umpired by a man."
Following his 6-3 7-5 3-6 2-6 7-6 (8) loss, Vallejo added: "It's very difficult for a woman to do it."
