Martin Wostenholme competed on the ATP World Tour for several years and managed to break into the Top 100 and achieve a career-high ranking of No. 84 in the world on November 11, 1985.
He received a tennis scholarship to Yale University which he attended from 1981-1984. During his time as a collegiate player, he was a four-time All-Ivy Leaguer in singles play.
Wostenholme developed great skill on clay, something rare for Canadians. He was a semifinalist at the Guaruja, Brazil Grand Prix event in 1988 and 1991 and was a semifinalist in the Rio de Janeiro Grand Prix event in 1990.
It seemed as if Wostenholme was always given a tough draw. His first Grand Slam appearance was at the 1985 US Open when he got past the first round, but fell to John McEnroe in the second round. A year later, in 1986 he made it to the second round of both the French Open and Wimbledon.
He advanced to the second round of the Australian Open in 1990, where he fell to Mats Wilander of Sweden. A few months later he competed at the French Open, this time he lost in the first round to American star Andre Agassi in four sets.
Wostenholme was the first Canadian to win a match at each of the four Grand Slam events.
Wostenholme was a Davis Cup member from 1980-1992, having reached the illustrious World Group in his final year. He posted an overall win-loss record of 12-8 in singles play.
Wanting to continue to grow tennis in the country, Wostenholme became a member of the board of directors for Tennis Canada and was named chair of the Tennis Development Committee in 2010.
