Xavier Malisse (born 19 July 1980) is a Belgian tennis coach and a former professional player. Born in the north-western Flemish city of Kortrijk and nicknamed X-Man, he is one of only two Belgian men (the other being David Goffin) to have been ranked in the top 20 of the ATP Tour, with a career-high singles ranking of world No. 19.
As a junior Malisse compiled a singles win–loss record of 66–18, reaching as high as No. 10 in the junior world singles rankings in 1997. He made the quarterfinals of Wimbledon in 1997, whilst his final junior tournament was winning Eddie Herr later that year.
After a difficult year, Malisse found himself with a world ranking of 205. In his first tournament of the year in Brisbane, he lost in the last qualifying round to American Bobby Reynolds. A week later, in Medibank International Sydney, he reached the main draw, but lost to Mario Ančić in the first round.
At the Australian Open, he first won his qualifying matches. In the first round of the main draw, he defeated Michaël Llodra. However, in the next round, he lost to Andy Roddick in four sets. In October, he won a Challenger tournament in Lyon, and this pushed him back into the world's top 100 for the first time in nearly two years.
He was banned for a year over doping allegations.[1][2]
Xavier started the 2011 season by reaching the final of Chennai.
In March, he won the doubles title in the Indian Wells Masters with Alexandr Dolgopolov of Ukraine. He reached the fourth round at Wimbledon, where he lost to Bernard Tomic.
Xavier reached the fourth round of Wimbledon where he faced Roger Federer. Federer won the first two sets and went a break up in the third, but Malisse came back to win the third set and move 2–0 in the fourth. Federer subsequently won six out of the next seven games to win the match and went on to win the Title.
After retiring in 2013 and competing in an ITF doubles event in 2015, Malisse entered the 2016 Meerbusch Challenger in doubles, ultimately conceding a walkover to end his playing career. He then participated in the ATP Champions Tour until 2018.
