Tiger Woods won the Buick Invitational for the third year in a row to make it seven PGA tournament wins on the spin, the longest winning streak since Byron Nelson's record 11 on August 4, 1945. Woods' sequence began with the British Open the previous year and ended at the Accenture World Matchplay in February.
Roger Federer won the Australian Open for the third time by beating Fernando González of Chile, who had helpfully disposed of Rafael Nadal in the quarter-finals. Federer was the first man to win a Grand Slam singles event without dropping a set since Björn Borg at the French Open in 1980.
Henri Rougier won the first Monte Carlo Rally. Not bad for someone who'd been driving for only two years. His car was a Turcat-Méry, built by Léon Turcat and Simon Méry, who'd been producing 'cars for the connoisseur' since 1899. The First World War and competition from mass-produced cars saw them go out of business in 1929. In the 1911 race, second and third places went to drivers in a Gobron and a Martini.
Parry O'Brien was born to be the most influential, innovative, and just about downright best shot putter of all time. When he climbed over a wire fence to start practising in the middle of the night because he had an idea that could not wait, he changed the event for ever. No-one else had ever turned their back on the direction of the throw. The new technique added space to the circle and greater thrust. Just as importantly, he was also the first shot putter to do regular weight training. He won the Olympic gold medal by two centimetres in 1952 and a safe margin in 1956. Then the taller American mammoths began to emerge, and O'Brien won silver at the 1960 Games and was still good enough to finish fourth in 1964. He won two golds at the Pan-American Games, set 14 world records, and was unbeaten for 117 competitions in a row.
Appearing in the final for the first time since losing easily to Martina Hingis in 1999, Amélie Mauresmo won the Australian Open by beating Justine Henin, who retired at 2-0 down in the second set after losing the first 6-1. There were no obvious signs of injury, but she complained of feeling unwell. Maybe it was something about Mauresmo herself. Henin was the third player to retire against her in the same tournament, following Kim Clijsters and Michaëlla Krajicek.
After their first summit meeting on 8 March 1971, we had to wait a while for Muhammad Ali - Joe Frazier II, which took place today and acted as an eliminator to fight George Foreman for the world title. Ali won on points, which spared Frazier a repeat of January 22.
In the 110 metres hurdles at the Commonwealth Games, Colin Jackson equalled his Commonwealth and European record of 13.11 seconds, then broke it in the final later in the day, running 13.08.
On the same day, Linford Christie won gold in the 100 metres. His time of 9.93 would have been a Games record but for a following wind. Australia's Jane Flemming set a Commonwealth record in winning the heptathlon, and her team mate Darren Clark won the 400 metres after being favourite for gold in 1986.
Canadian snooker player Kirk Stevens made a 147 maximum against Jimmy White at the Masters.
Defending champion Andre Agassi beat Arnaud Clément in three easy Australian Open sets. Clément had left some of his strength behind in the semi-final, saving match points as he came from two sets down to beat his friend and doubles partner Sébastien Grosjean. But Agassi had also played five sets in the semis, outlasting a cramping Pat Rafter.
Quarterback Trent Dilfer helped Baltimore Ravens win 34-7 against New York Giants, who'd released him the previous season. One of Baltimore's touchdowns was scored by 21-year-old Jamal Lewis, who was the youngest player in any Super Bowl.
In the most one-sided Super Bowl of all, San Francisco 49ers thrashed Denver Broncos 55-10. It was a day of records. Quarterback Joe Montana became the only player to be made Super Bowl Most Valuable Player three times. He threw five touchdown passes, three of them to Jerry Rice. Montana's career total of 11 touchdown passes is another Super Bowl record. In complete contrast, his opposite number John Elway finished on the losing side in a Super Bowl for the third time. He sneaked a touchdown, but close-ups of his face showed a man who'd been publicly traumatised. He didn't get a chance to exorcise these demons until 25 January eight years later.
Ivan Lendl was lucky to retain the Australian Open title. Stefan Edberg won the opening set and served for the second at 6-5. But he had torn a stomach muscle right at the start, and Lendl forced a tie-break, which he won. Edberg retired during the third set.
The English Open used to be one of the big events in table tennis, second only to (and older than) the World Championships. Today Desmond Douglas won the singles title for the second time. No British player has won it since. Douglas recovered from two games down to beat the unseeded young Yugoslav Vladislav Broda.
Dallas Cowboys won the Super Bowl for the third time in four years and the fifth in all by beating Pittsburgh Steelers 27-17.
Nick Price was born in Durban, but became a Zimbabwean citizen. It took him a while to reach the very top in golf, but once he did he stayed there a while. After finishing runner-up at the British Open in 1982 and 1988, he finally won it in 1994, shooting a superb 268 to finish one shot ahead of Sweden's Jesper Parnevik, who dropped a shot at the last because he apparently misunderstood what he needed. Price followed this up by winning the very next Major, the USPGA, which he also won in 1992. He was the first golfer in 70 years to win the British Open and the PGA in the same year.
Big-hitting Scotsman Chic Calderwood won the vacant British light-heavyweight title by stopping Arthur Howard in the 13th. He was stripped of it in 1963 and died in a car crash in 1964.
For a while, Emma George was the star of women's pole vaulting. She set 12 world records, including two today in Perth, when she broke her own best with 4.30 metres then shattered it with 4.41. She was the first woman to clear 4.50 and 4.60.
Jerzy Szczakiel was born in Poland. He was the shock world speedway champion in 1973, when the final was held in his home country. Shock or not, he held his poise - and stayed on his bike - to win a run-off with the great Ivan Mauger, who fell during the race. Szczakiel was world pairs champion in 1971, when the event was also held in Poland.
