Question: Kim Warwick and Matt Lucena both play what sport?
Context: The origins of the Brisbane International trace back to the early 1970s, when the Grand Prix tennis circuit, formed in 1970, and which ran concurrently with other tours as the World Championship Tennis circuit, decided to feature on its calendar an event in Queensland to develop a South West Pacific season around the Australian Open - then taking place in Brisbane - alongside other Oceanian events of Sydney, New South Wales; Hobart, Tasmania; and Auckland, New Zealand.  The Adelaide-based South Australian Tennis Championships, running as an amateur, then as a State championship, since 1889, were brought to the professional circuit in 1972.  The first professional edition of the men's event, played, like the Australian Open, on outdoor grass courts, saw the victory of Soviet Alex Metreveli over Kim Warwick, while the women's event, still not featured in either the Commercial Union Grand Prix circuit or the Virginia Slims circuit, saw Australian Evonne Goolagong win the title. Matt Lucena (born August 4, 1969) is a former professional tennis player from the United States.  He won the mixed doubles title at the 1995 US Open. The Men's Doubles tournament at the 1980 Australian Open was held from 26 December 1980 through 4 January 1981 on the outdoor grass courts at the Kooyong Stadium in Melbourne, Australia.  Mark Edmondson and Kim Warwick won the title, defeating Paul McNamee and Peter McNamara in the final. Meredith McGrath and Matt Lucena were the defending champions but only Lucena competed that year with Kimberly Po. John McEnroe was the defending champion and won the singles title at the 1980 Queen's Club Championships tennis tournament defeating Kim Warwick in the final 6–3, 6–1. Mark Edmondson and Kim Warwick were the defending champions, but Warwick did not participate this year.  Edmondson partnered Tomáš Šmíd, losing in the semifinals. The Cedar Grove Open is a defunct tennis tournament that was played on the Grand Prix tennis circuit in 1974.  The event was held in Cedar Grove, New Jersey.  Ilie Năstase won the singles title while Kim Warwick and Steve Siegel partnered to win the doubles title. This is a list of the main career statistics of Australian former tennis player Evonne Goolagong.  During her career, which lasted from 1967 to 1983, Goolagong won seven singles titles at a Grand Slam event and was a runner-up on 11 occasions.  In addition she won five Grand Slam doubles titles, partnering Margaret Court, Peggy Michel and Helen Gourlay, as well as one mixed doubles title with Kim Warwick.  In total she won 82 singles titles, 46 doubles titles and 4 mixed doubles titles.  She achieved a No. 1 singles ranking for a two-week period in April–May 1976 although this was only officially recognized in 2007.  She was a member of the Australian Federation Cup teams that won the cup in 1971, 1973 and 1974. Kim Warwick (born 8 April 1952) is an Australian former professional male tennis player who competed on the ATP Tour from 1970–1987 reaching the final of the singles Australian Open in 1980.  He defeated over 35 players ranked in the top 10 including Guillermo Vilas, Raul Ramerez, Vitas Gerulaitis, Jan Kodeš, Bob Lutz and Arthur Ashe.

Partnering with Evonne Goolagong, he won the French Open 1972, defeating Françoise Dürr and Jean-Claude Barclay in the final 6–2, 6–4.  Evonne and Kim were finalists in 1972 at Wimbledon against Rosie Casals and Ilie Năstase who won 6–4, 6–4. Kim Warwick won the title, defeating Bernard Mitton 7–5, 6–4 in the final.
