Bill Tilden wrote of the pair that he had "seldom seen a team work together more smoothly than the Kinseys."[3] In 1926, he reached the Wimbledon final, losing to Jean Borotra.[4]
Kinsey was ranked world No. 7 in 1924 by A. Wallis Myers in his amateur rankings for The Daily Telegraph.[1] As a pro, American Lawn Tennis Magazine ranked Kinsey as world No. 6 in 1930.[5]
Later in 1926, he was one of the early players signed by the promoter Charles C. Pyle to play in his professional tennis league. After a split with Pyle, he joined Richards in forming an association of professional tennis players.[6]
In 1936, he and Helen Wills Moody volleyed a tennis ball back and forth 2,001 times without missing. The feat took them 1 hour and 18 minutes. They only stopped the exchange so that Kinsey could go teach a lesson that he had scheduled.
Kinsey is a member of the USTA Northern California Hall of Fame.[7]
