Kenneth Robert Rosewall  (born 2 November 1934) is a former world top-ranking amateur and professional tennis player from Australia. He won a record 23 tennis Majors including 8 Grand Slam singles titles and, before the Open Era, a record 15 Pro Slam titles; overall, he reached a record 35 Major finals. He won the Pro Grand Slam in 1963. Rosewall won 9 slams in doubles with a career double grand slam.
From August 1972 players could enter almost all the tournaments they wanted and the real open era began (at Forest Hills they created the ATP) Rosewall won seven tournaments in 1972, including the depleted Australian Open and became the oldest Grand Slam male singles champion (37 years and 2 months old) in the open era, and was ranked, by Judith Elian or Tingay or McCauley, No. 3 behind Smith and Ilie Nastase (Bud Collins permuting Nastase and Rosewall). He lost in the second round of the 1972 U.S. Open against Mark Cox. For Rosewall the beginning of 1973 was identical to the second half of 1972: a desert. He recorded possibly his worst defeat in his whole career at the 1973 Australian Open (again with a weak field because as in 1972 among the Top 20 only Rosewall and Newcombe participated) when seeded first he was defeated by German Karl Meiler in his first match (second round) in straight sets: 2-6, 3-6, 2-6. Between May 1972 (victory at Dallas) and April 1973 (victory at Houston, River Oaks) Rosewall captured only two minor titles, Tokyo WCT (not giving points for the WCT Finals) and Brisbane (in December 1972) where he was the only Top 20 player. If 1967 has been the first year of a relative decline with however many highlights, 1973 (and more accurately his "after-Dallas 1972") has been the real start of Rosewall's true decline : admittedly he was still one of the best players but not one fighting for the first place. Rosewall did not play Wimbledon that year as the edition was boycotted by the ATP players. After an absence of 17 years Rosewall returned to Davis Cup play in November when he played a doubles match with Rod Laver in the interzonal final against Czechoslovakia. His best performances in 1973 were firstly his semifinal at the US Open (as in 1972 the greatest event of the year) and secondly his third place at the WCT Finals (he was beaten by Ashe in the semifinals and defeated Laver for 3rd place). He also won at Houston WCT, Cleveland WCT, Charlotte WCT, Osaka and Tokyo. He was still ranked in the top 10. Tommasi ranked Rosewall 4, Tingay 6, ATP 6, Collins 5, and McCauley 7.
