Ivan Dupasquier (born 23 November 1961) is a former professional tennis player from Switzerland.[1]
Dupasquier made his Davis Cup debut in 1980, when he lost a dead rubber singles match to Italy's Gianni Ocleppo. His next match, which he won, was against Mexican Juan Hernández the following year. In 1982 he won a singles rubber over Mohammed Dlimi of Morocco, to finish with a 2-1 Davis Cup career record.[2]
The Swiss player was granted "special exempt status" by the organisers of the 1981 US Open. This was because he was busy playing a Davis Cup tie during qualifying and meant that he would go straight into the main draw.[3] He lost to Mark Edmondson in the opening round.[4] Also that year he reached the quarter-finals of the Taipei Grand Prix tournament and was a losing finalist in Manila.[4]
He completed in the men's doubles draw of a Grand Slam event on one occasion, which was at the 1982 French Open, where he partnered Christophe Roger-Vasselin.[4] They didn't make it past the first round.[4]
