Background: Gregory John Norman AO (born 10 February 1955) is an Australian professional golfer and entrepreneur who spent 331 weeks as the world's Number 1 Official World Golf Rankings ranked golfer in the 1980s and 1990s. He has won 91 international tournaments, including 20 PGA Tour tournaments and two majors: The Open Championships in 1986 and 1993. Norman also earned thirty top-10 finishes and was the runner-up 8 times in majors throughout his career.
Context: Norman endured another setback at the 1987 Masters. In his final round on the 18th green, Norman had a 20-foot putt for a birdie that would win the tournament. The ball trickled over the left lip of the cup, missing by millimetres. After Norman's par on the 72nd hole at Augusta, he found himself in a sudden-death playoff with Larry Mize and Seve Ballesteros. On the second playoff hole, with Ballesteros eliminated, Mize holed a 47-yard (140-foot) chip to win the tournament. Norman did, however, win the Australian Masters in February 1987 and the Australian Open later in the year by a record ten shots at Royal Melbourne Golf Club, beating the previous Australian Open record winning margin of eight strokes by Jack Nicklaus in 1971. Norman's 1987 victory at the Australian Open lifted him back above Seve Ballesteros to the top of the Official World Golf Ranking. Norman had another four wins in Australia in 1988. In the U.S., Norman won the MCI Heritage Golf Classic at Hilton Head Island, South Carolina in April 1988, inspired by a leukemia-stricken teenager who got his wish to meet Norman and watch him play. The teenager was only supposed to watch the golfer for two rounds, but Norman arranged for him to stay until the tournament's completion. After the tournament, Norman awarded the teen with the trophy. He was inducted into the Sport Australia Hall of Fame in that year. At the 1989 Masters, Norman missed a 12-foot par putt on the 72nd hole which would have put him into a playoff with Nick Faldo and Scott Hoch. Norman had another chance at a major in 1989, this time at the Open Championship at Royal Troon. He played a final-round of 64, starting his round with six straight birdies, to force his way into a playoff with Mark Calcavecchia and Wayne Grady. Going into the final playoff hole, Norman and Calcavecchia were tied, but two successive bunker shots by Norman gave Calcavecchia the victory. Norman won the Doral-Ryder Open and Memorial Tournament in March 1990 after having missed the cut for the first time at the 1990 Masters. In the 1990 Open Championship at St Andrews, Norman began with two rounds of 66, leaving himself sharing the lead with Nick Faldo after 36 holes and the pair four shots ahead of the rest of the field. Faldo then shot a third round of 67, but Norman could only manage 76. Norman finished the tournament tied for sixth place, while Faldo won by five shots. Although 1990 was not Norman's strongest majors year, he finished at the top of the PGA Tour money list for the second time in his career and won the Vardon Trophy and Byron Nelson Award. Later that year, he won the Australian Masters in his home country for a final and record sixth time.

Background: Fliehr was born on February 25, 1949 in Memphis, Tennessee. His birth name is widely perceived to be Fred Phillips, although on different documents, he is also credited as Fred Demaree or Stewart, while his biological parents were Luther and Olive Phillips (the latter of which was also credited under the Demaree and Stewart surnames). He was adopted, and at the time of his adoption (arranged by the Tennessee Children's Home Society), his father, a physician, was completing a residency in Detroit. Shortly afterward, the family settled in Edina, Minnesota, where the young Fliehr lived throughout his childhood and after ninth grade he attended Wayland Academy, a coeducational boarding school in Beaver Dam, Wisconsin, for four years (five years total in high school), during which time he participated in interscholastic wrestling, football and track.
Context: Flair signed with the World Wrestling Federation (WWF) in September 1991 and began appearing on television with the Big Gold Belt, calling himself "The Real World Champion". Led by his "financial adviser" Bobby Heenan and his "executive consultant" Mr. Perfect, Flair repeatedly issued challenges to WWF wrestlers like "Rowdy" Roddy Piper and Hulk Hogan, wrestling a team led by Piper at Survivor Series in November 1991 and helping The Undertaker defeat Hogan for the WWF Championship that same night. WCW sued Flair in an attempt to reclaim the championship belt, but Flair claimed that he owned the title belt in lieu of the US$25,000 deposit paid by NWA champions upon winning the title, which had not been returned to him when he was fired from WCW. At the 1992 Royal Rumble, Flair won the Rumble match to claim the vacant WWF Championship. Flair entered as number three in the Rumble match and lasted 60 minutes, last eliminating Sid Justice with help from Hulk Hogan, who had been eliminated by Justice seconds earlier. Randy Savage then challenged Flair for the WWF Championship as part of the double main event at WrestleMania VIII. In the storyline, Flair taunted Savage by claiming that he had a prior relationship with Savage's wife, Miss Elizabeth. Savage defeated Flair for the title at WrestleMania. In July 1992, as Savage prepared to defend the title against The Ultimate Warrior at SummerSlam, Flair and Mr. Perfect sowed distrust between the two by suggesting that they would back one or the other during their match. They actually attacked both Savage and Warrior and injured Savage's knee, an injury that Flair exploited to regain the title in a match with Savage on September 1. His second reign was short-lived, however, as he lost the title to Bret Hart on October 12, 1992. Flair teamed with Razor Ramon to take on Savage and Perfect at the Survivor Series in November 1992. Flair appeared in the Royal Rumble in January 1993, then lost a Loser Leaves the WWF match to Mr. Perfect on the next night's (January 25) Monday Night Raw in a match taped six days earlier. Flair then fulfilled his remaining house show commitments, making his last appearance on February 10, 1993, before returning to WCW.
