Ian McInnes (1901–1977) was an Australian tennis player. He was also a medical doctor.[2] At the 1923 U.S. Championships, McInnes lost in the second round to Manuel Alonso Areizaga.[3] At the 1924 Australasian championships, McInnes caused a huge upset by beating two-time Wimbledon champion Gerald Patterson. Patterson twisted his ankle in the first set and, because of this, his game was affected and he played mainly from the baseline.[4] McInnes lost in the quarter-finals to Richard Schlesinger.[5] McInnes lost in the second round of the 1927 Australian championships to Rice Gemmell[6] In 1967 McInnes attended Gerald Patterson's funeral.[2]
