Question: Who won more Grand Slam Titles Sue Barker or Arthur Ashe ?
Context: Kenneth Robert Rosewall {'1': ", '2': ", '3': 'AM, MBE', '4': "} (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 and a record 35 Major finals overall.  He won the Pro Grand Slam in 1963.  Rosewall won 9 slams in doubles with a career double grand slam.  He is considered to be one of the greatest tennis players of all time.  He had a renowned backhand and enjoyed a long career at the highest levels from the early 1950s to the early 1970s.  Rosewall was one of the two best male players for about nine years and was the World No. 1 player for a number of years in the early 1960s.  He was ranked among the top 20 players, amateur or professional, every year from 1952 through 1977.  Rosewall is the only player to have simultaneously held Pro Grand Slam titles on three different surfaces (1962–1963).  At the 1971 Australian Open he became the first male player during the open era to win a Grand Slam tournament without dropping a set. The Grand Slam tournaments, also called majors, are the four most important annual tennis events.  They offer the most ranking points, prize money, public and media attention, the greatest strength and size of field, and greater number of "best of" sets for men.  The Grand Slam itinerary consists of the Australian Open in mid January, the French Open in May and June, Wimbledon in July, and the US Open in August and September.  Each tournament is played over a period of two weeks.  The Australian and United States tournaments are played on hard courts, the French on clay, and Wimbledon on grass.  Wimbledon is the oldest, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905.  However, of these four, only Wimbledon was a major before 1924–25, when all four became designated Grand Slam tournaments.  Skipping Grand Slam tournaments—especially the Australian Open because of the remoteness, the inconvenient dates (around Christmas and New Year's Day) and the low prize money—was not unusual before 1982, which was the start of the norm of counting Grand Slam titles. Susan Barker, OBE (born 19 April 1956 in Paignton, Devon) is an English television presenter and former professional tennis player.  During her tennis career, she won eleven WTA Tour singles titles, including one Grand Slam singles title at the 1976 French Open.  She reached a career-high singles ranking of World No. 3.  She is now one of the main sports presenters at the BBC, most notably fronting the corporation’s coverage of Wimbledon and A Question of Sport. The Williams sisters are two professional American tennis players: Venus Williams (b. 1980), a seven-time Grand Slam title winner (singles), and Serena Williams (b. 1981), twenty-three-time Grand Slam title winner (singles), both of whom were coached from an early age by their parents Richard Williams and Oracene Price.  There is a noted professional rivalry between them – between the 2001 US Open and the 2017 Australian Open tournaments, they met in nine Grand Slam singles finals.  They became the first two players, female or male, to play in 4 consecutive grand slam singles finals from the 2002 French Open to the 2003 Australian Open; Serena famously won all 4 to complete the first of two "Serena Slams".  Between 2000 and 2016, a 17-year span, they collectively won 12 Wimbledon singles titles (Venus won 5 and Serena won 7).  By winning the 2001 Australian Open women's doubles title, they became the 5th pair to complete the Career Doubles Grand Slam and the only pair to complete the Career Doubles Golden Slam.  At the time, Venus and Serena were only 20 and 19 years old, respectively.  Since then they have gone on to add another two Olympic gold medals in the 2008 Beijing Olympics and the 2012 London Olympics.  Nearly a decade later, the duo would go on to win 4 consecutive grand slam doubles titles from 2009 Wimbledon through 2010 Roland Garros, which would catapult them to co-No.  1 doubles players on 7 June 2010.  Two weeks later, on 21 June 2010, Serena would hold the No. 1 singles ranking and Venus would be right behind her at No. 2 in singles.  Their most recent grand slam doubles titles came at the 2012 Wimbledon & 2016 Wimbledon events.  They remain very close, often watching each other's matches in support, even after one of them has been knocked out of a tournament. Carlos Fernandes (1936-) is a retired Brazilian tennis player.  He had a good all-round game with excellent passing shots and moved fast around the court.  Fernandes had a reputation for being a charismatic ladies man.  He later became a coach.  He made his Grand Slam debut at Wimbledon 1957, losing in the opening round to Jorgen Ulrich.  At Roland Garros in 1958, Fernandes lost in round one to Pierre Darmon.  At Wimbledon he lost in round one to Butch Buchholz.  At 1959 French Open, Fernandes lost in round three to Jacques Brichant.At Wimbledon he lost in round two to Neale Fraser.  At French Open 1960, Fernandes lost in round three to Bobby Wilson and at Wimbledon lost in round two to Wolfgang Stuck.  At 1961 French Open, Fernandes achieved his best Grand Slam singles result by beating Pierre Darmon and Bob Hewitt before losing to Jan-Erik Lundquist in the quarter finals.  He lost in round two of Wimbledon to Wilson.  At Roland Garros 1962, Fernandes lost to Lundquist in round two.  At Wimbledon he lost in round one to Neale Fraser's brother John.  At 1963 French Open he lost in round one to Christian Duxin.  In round one of Wimbledon he led a young Arthur Ashe by two sets to 0, but lost in five sets.  At Wimbledon 1964 he lost in round two to Gene Scott.  An ankle injury in 1964 took its' toll and Fernandes played less after that.  As Open tennis arrived, Fernandes was reaching the end of his career.  He lost in round one of 1968 French Open to Bernard Montrenaud.  At Wimbledon he lost in round one to Mike Sangster. The Arthur Ashe Courage Award (sometimes called the Arthur Ashe Award for Courage or Arthur Ashe for Courage Award) is an award that is part of the ESPY awards.  Although it is a sport-oriented award, it is not limited to sports-related people or actions, as it is presented annually to individuals whose contributions "transcend sports".  Often these figures are also athletes who have been at the top of their sport, such as Muhammad Ali, Dean Smith, and Cathy Freeman. Arthur Robert Ashe Jr. (July 10, 1943 – February 6, 1993) was an American professional tennis player.  He won three Grand Slam titles. Larisa Savchenko-Neiland (née Savchenko; born 21 July 1966) is a former professional tennis player who represented the Soviet Union and Latvia.

She also won two singles titles and sixty-five doubles titles. The 1968 US Open (formerly known as U.S. National Championships) was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club, Forest Hills in New York, United States.  The tournament ran from 29 August until 8 September.  It was the 88th staging of the tournament and the fourth Grand Slam event of 1968.  It was the first edition of the tournament in the Open Era of tennis and as such for the first time offered prize money, totaling $100,000.  Arthur Ashe and Virginia Wade won the singles titles.  Ashe was still registered as an amateur and therefore not entitled to the $14,000 first-prize money, which instead went to runner-up Tom Okker, while Wade earned $6,000.  Frank Parker, at the age of 52, lost to eventual champion Arthur Ashe in the second round, and still holds the record for the oldest man to compete in a Grand Slam singles tournament.
