Question: Which tennis player is older, Billy Martin or Pavel Složil?
Context: Andrei Pavel (born 27 January 1974 ) is a Romanian tennis coach and former professional tennis player.  He is currently coaching the world no. 2 tennis player, Simona Halep, along with Darren Cahill. Billy Martin (1928–1989) was a Major League Baseball player and manager. Petr Pála (born 2 October 1975) is a former professional tennis player from the Czech Republic.  Together with Pavel Vízner he reached the men's doubles final of the 2001 French Open but lost to Indians Mahesh Bhupathi and Leander Paes (6–7, 3–6).  Pála was coached by his father František, who was a professional tennis player on the ATP tour. American tennis player Pancho Gonzales had a long-running rivalry with Australian Ken Rosewall.  Gonzales is still sometimes considered to be a candidate for the greatest tennis player of all time; he was the dominant player of the 1950s and still holds the men's all-time record of being ranked world No. 1 for eight years.  Rosewall became the world's best player upon Gonzales's semi-retirement in 1961 and held that position either by himself or sharing it with others for six years.  Rosewall was signed in 1956 by the promoter Jack Kramer, a former #1 player himself, to join his small band of touring professionals in 1957.  He then engaged in a round-the-world, head-to-head tour against Gonzales, the defending world's champion, over the next five months, winning 26 matches but losing 50.  In his 1979 autobiography Kramer included both Gonzales and Rosewall in his list of the 21 greatest players of all time.  Kramer, however, initially "panicked" upon signing Rosewall.He was a cute little fellow with a dink serve, who operated mostly from the baseline.  That great volley of his hadn't been developed yet.  I was afraid that Gorgo would eat him alive and put us out of business the rest of the way.  But like a lot of people I completely underestimated Rosewall.  Before their opening match in Melbourne, Kramer went to Gonzales and asked him to "carry" Rosewall, giving him a better share of the gate to gain his assent.  Gonzales did try to carry out his part of the deal for a few matches, but then called it off, telling Kramer that he was no longer able to play his normal game.  Kramer agreed.  "It was... obvious that Rosewall was not the pushover I had feared.  (In fact, Gonzales only beat him 50–26, and it was always competitive.)"  Six years older than Rosewall, 13 years later, in 1970, Gonzales defeated him in 6–4, 6–4, in the 199th and next-to-last match they ever played—Gonzales was 42 years old at the time and Rosewall was considered to be the co-No.  1 player in the world. Pavel Složil (born 29 December 1955) is a former professional tennis player from Czechoslovakia. Billy Martin (born December 25, 1956, in Evanston, Illinois, United States), is a right-handed former professional tennis player from the United States.  During his career he won 1 singles titles and 3 doubles titles.  He achieved a career-high singles ranking of World No. 32 in 1975.  Martin currently serves as the head coach for the UCLA Bruins men's tennis team, a position he has held for the past 24 years since 1994.  Martin, who played at UCLA, has a 14 straight top 5 NCAA team finishes and a 9 consecutive 20-win seasons.  He was named ITA (Intercollegiate Tennis Association) division 1 National Coach of the Year and is a member of ITA Hall of Fame. Gene Ellis "Mickey" Klutts (born September 20, 1954) is a retired Major League Baseball player who played in the Major Leagues from 1976 to 1983 with the New York Yankees, Oakland Athletics and Toronto Blue Jays.  An infielder, Klutts was a favorite of manager Billy Martin, for whom he played in both New York and Oakland. The Laguna Niguel Classic is a defunct tennis tournament that was played on the Grand Prix tennis circuit in 1977.  The event was held in Laguna Niguel, California and was played on outdoor hard courts.  Andrew Pattison won the singles title while James Chico Hagey and Billy Martin partnered to win the doubles title. Reginald "Reggie" or "R. F." Frank Doherty (14 October 1872 – 29 December 1910) was a British tennis player and the older brother of tennis player Laurence Doherty.  He was known in the tennis world as "R.F." rather than "Reggie".  He was a four-time Wimbledon singles champion and a triple Olympic Gold medalist in doubles and mixed doubles. The 1981 Lorraine Open was a men's tennis tournament played on Indoor carpet courts.  The event was part of the 1981 Volvo Grand Prix and was played in Nancy in France.  It was the third edition of the tournament and was held from 16 March through 22 March 1981.  Seventh-seeded Pavel Složil won the singles title.
