Question: Which tennis player is older, Roy Emerson or Wayne Black?
Context: Wayne Hamilton Black (born 17 November 1973 in Harare, is a former professional male tennis player from Zimbabwe. Roy Stanley Emerson (born 3 November 1936) is an Australian former World number one tennis player who won 12 Major singles titles and 16 Grand Slam tournament men's doubles titles.  He is the only male player to have completed a Career Grand Slam (winning titles at all four Grand Slam events) in both singles and doubles.  His 28 major titles are an all-time record for a male amateur player.  Emerson is the first male player to win each amateur major title at least twice in his career.  He is one of only eight men to win all four majors in his career.  He was the first male player to win 12 majors.  Along with Novak Djokovic, he is one of only two male players to win six Australian Championships.  He won five of them consecutively (1963–67).  His 12 wins have since been surpassed.  Emerson is one of only five tennis players all-time to win multiple slam sets in two disciplines, only matched by Margaret Court, Martina Navratilova, Frank Sedgman and Serena Williams. Francis "Frank" Arthur Sedgman, AM (born 29 October 1927) is a retired former World No. 1 amateur tennis champion.  In his 1979 autobiography Jack Kramer, the long-time tennis promoter and great player himself, included Sedgman in his list of the 21 greatest players of all time.  Sedgman, Kramer wrote, "was as quick as anybody who ever played the game, but he couldn't keep the heat on."  Sedgman is one of only five tennis players all-time to win a multiple slam set in two disciplines, matching Margaret Court, Roy Emerson, Martina Navratilova and Serena Williams.  In 1951 he and Ken McGregor won the men's doubles Grand Slam.  Sedgman turned professional in 1953. Gilbert Shea (born 5 October 1928) is a former American tennis player.  Although born in Oregon, Shea and his family moved to California when he was three years old.  He started playing tennis when he was around eight years old.  Big serving Shea was ranked as high as number 4 in the U. S. in 1957.  Making his Grand Slam debut at the U. S. championships in 1948, Shea lost in round three to Jaroslav Drobny.  In 1949 he lost in round two to Edward Moylan and in 1950 lost in round one to Hugh Stewart.  At the 1952 U. S. Championships, Shea lost in round three to Mervyn Rose.  In 1953 he lost in round three to Arthur Larsen.  At Roland Garros in 1954 Shea lost in round three to Jaroslav Drobny.  At Wimbledon, he lost in the last 16 to Rex Hartwig.  At the U. S. Championships, he beat Luis Ayala before losing in round three to Moylan.  At Wimbledon 1955, Shea beat Vic Seixas and Adrian Quist before losing in the last 16 to Nicola Pietrangeli.  He lost in round one of the U. S. championships.  At the 1956 Australian championships, Shea beat a young Roy Emerson (who won 6 titles in the 1960s) before losing in the quarter finals to Neale Fraser.  Shea lost in round two of Wimbledon.  He reached the last 16 at U. S. championships, losing to Fraser.  In 1957 Shea lost in round two of Roland Garros, round one of Wimbledon and round three at U. S. championships.  Shea then lost in round one of Wimbledon 1958 and round two at U. S. championships in 1959 and then retired.  In later life he played a lot of golf recreationally. Ronald McKenzie is a New Zealand professional male tennis player who reached the final of ATP Auckland Open in 1960, where he lost to Roy Emerson 6–3, 6–1, 6–1. Australian tennis player Rod Laver had a long rivalry with his fellow Queenslander Roy Emerson.  They met first on the senior amateur tour in 1958 and dominated the amateur circuit until 1962, before Laver went pro.  When open tennis arrived in 1968, Emerson went pro, and had many new battles with Laver. The 1973 Denver WCT, also known as the 1973 United Bank Tennis Classic for sponsorship reasons, was the second edition of the tennis event.  It was held on indoor carpet courts in Denver, Colorado.  The tournament was held between the 23 April and 30 April.  The tournament was part of the World Championship Tennis tour, and was part of the Group B circuit.  As a result the defending champions Rod Laver, of the doubles and singles, along with his doubles partner Roy Emerson, were ineligible to compete. Antony Emerson (29 March 1963 – 23 January 2016) was a professional tennis player from Australia.  He was the son of Roy Emerson. The 1968 Buenos Aires tennis tournament was a combined men's and women's tennis tournament played on outdoor clay courts at the Buenos Aires Lawn Tennis Club in Buenos Aires in Argentina.  It was the first open edition of the tournament and was held from 4 November through 11 November 1968.  Roy Emerson and Ann Jones won the singles titles.
