Gaston Gaudio, who won the French Open in 2004, officially announces his retirement in an interview with Argentine television.
Gaudio, who has not played in about a year, said he retired "long ago" but waited to see whether he would change his mind before making any announcements.
"At first it was complicated, many years playing and many joys and sadnesses, but it passed," he said. "I could play exhibitions, but I'm not coming back."
He has not ruled out eventually becoming a coach.
