Tennis Trivia and World Sports Quiz

Steffi Graf became the first defending champion to lose in the first round of a Grand Slam when she was defeated by Lori McNeil at the 1994 French Open. This was a historic upset as Graf was the reigning champion and had won the title the previous year. Graf later won the French Open three more times, showing her dominance on clay despite this early exit.

Björn Borg is the only men's player to win three Grand Slam titles without losing a set - accomplishing this feat at the 1978 French Open and 1976-77 Wimbledon. While Ken Rosewall won majors without dropping a set, he achieved this fewer times. Roger Federer and Don Budge never completed a Grand Slam tournament without dropping a set. Borg's efficiency on clay and grass was remarkable during his prime.

Wimbledon introduced the retractable roof over Centre Court in 2009 to prevent rain delays that had plagued the tournament for years. The roof takes about 10 minutes to close and allows play to continue during rain showers. Hawk-Eye was introduced earlier (2002), radar guns for serve speeds were already in use, and artificial turf has never been used at Wimbledon.

Goran Ivanisevic set the record for most aces in a calendar year by hitting 1,477 aces in 1996. His powerful serve was his greatest weapon, and he led the ATP Tour in aces multiple times during his career. While players like Ivo Karlovic have higher career ace totals, Ivanisevic's single-season record remains unmatched. Mark Philippoussis and Greg Rusedski were also big servers but never approached this seasonal total.

Martina Hingis stormed off court after losing the first set of the 1999 French Open final against Steffi Graf. She had to be coaxed back to continue the match by her mother and coach Melanie Zogg-Sulberger. Hingis eventually returned but lost the match in straight sets. This incident reflected the intense pressure and emotional nature of championship matches.

Andy Roddick hit the fastest recorded serve at 155 mph during a 2004 Davis Cup match. His powerful serve was his signature shot throughout his career. Ivo Karlovic has consistently been among the fastest servers on tour, but Roddick's 155 mph remains the official ATP record. Greg Rusedski and Mario Ancic were also known for big serves but never reached this speed.

Björn Borg reached the US Open final four times (1976, 1978, 1980, 1981) but lost each time to players like Jimmy Connors and John McEnroe. Despite winning five consecutive Wimbledon titles and six French Opens, Borg never captured the US Open trophy. His four final losses make him the player with the most US Open final appearances without a victory in the Open Era.

Tennis was introduced as an Olympic sport in the first modern Olympics in 1896 in Athens. John Boland of Ireland won the men's singles title. Tennis was dropped from the Olympics after 1924 and returned as a demonstration sport in 1968 and 1984 before becoming a permanent medal sport again in 1988. The 1896 introduction makes tennis one of the original Olympic sports.

Monica Seles was stabbed on April 30, 1993 during a changeover in her match against Magdalena Maleeva at the Citizen's Cup tournament in Hamburg. The attacker was a deranged fan of Steffi Graf who wanted to help Graf regain the world No. 1 ranking. Maleeva was not involved in the incident - she was Seles' opponent on court when the attack occurred during a break in play.

Jimmy Connors won the US Open on grass at Forest Hills in 1974, on clay at Forest Hills in 1976, and then on hard courts at Flushing Meadows in 1982 and 1983. This makes him unique as the only player to have won the US Open on three different surfaces before the tournament permanently moved to hard courts. McEnroe won only on hard courts, Borg never won the US Open, and Sampras won only on hard courts.

Andre Agassi was the first man to win all four Grand Slam tournaments (Australian Open, French Open, Wimbledon, US Open) on three different surfaces - hard, clay, and grass. He completed the career Grand Slam by winning the French Open in 1999. Laver won all four in the same year (1969) but on just two surfaces (grass and clay), Emerson and Perry never achieved the career Grand Slam on all surfaces.

Ken Rosewall, the Australian tennis great, was nicknamed 'Muscles' due to his slight and wiry build - the nickname was ironic. He was one of the finest players of the 1950s and 1960s, known for his exceptional backhand and longevity in the sport. Borg was known as 'The Ice Man', Perry as 'The Last Brit', and Budge was called 'Don' rather than having a famous nickname.

The US Open is the only Grand Slam tournament that uses a tie-break in the final set. Since 1970, the US Open has employed a tie-break at 6-6 in the final set, unlike Wimbledon, French Open, and Australian Open which require players to win by two games in the final set (though Wimbledon has since introduced a special tie-break at 12-12). This makes the US Open unique among the majors in its final-set format.

Rugby Union is widely recognized as New Zealand's national sport, with the national team (the All Blacks) being one of the most successful and iconic teams in international rugby. While cricket is also popular, rugby holds a special place in New Zealand's culture and identity.

Archery is officially recognized as Bhutan's national sport and has deep cultural and historical significance in the country. It is played during festivals and celebrations, reflecting Bhutan's rich sporting traditions.

Volleyball is officially the national sport of Sri Lanka, declared in 1991, though cricket is immensely popular and often considered the de facto national sport due to the country's success in international cricket. This question tests the official designation.
