Sports Records and History

Roger Federer's coach during the 2005 season was Tony Roche, who coached him from 2005-2007. Roche was a former Australian tennis player who helped Federer during his peak years. The other names are not associated with coaching Federer during this period.

Roy Emerson held the record for the most combined Grand Slam titles (singles and doubles) with 28 titles for many years during the amateur and early Open Era. This included 12 Grand Slam singles titles and 16 doubles titles, a record that stood until modern era players surpassed it in the 2000s.

Arthur Ashe won the first US Open in 1968, defeating Tom Okker. This was a historic victory, making Ashe the first African American man to win a Grand Slam singles title.

The US Open switched to blue courts in 2005, specifically to improve television visibility. The blue color provides better contrast with the yellow tennis ball.

Tracy Austin won the US Open in 1979 at age 16, making her the youngest Womens Singles champion. Martina Hingis won later but was slightly older.

Juan Martin del Potro won the 2009 US Open men's singles title, defeating Roger Federer in a five-set final. This was del Potro's first and only Grand Slam victory, making him the first Argentine to win the US Open since 1977.

Sebastian Vettel became the youngest Grand Prix winner at age 21 when he won the 2008 Italian Grand Prix for Toro Rosso. (Note: Max Verstappen later broke this record, but in the context when this question was written, Vettel held the distinction.)

Kim Clijsters made a stunning comeback to tennis by winning the 2009 US Open women's singles title, defeating Caroline Wozniacki in the final.

Richard Krajicek won his only Grand Slam at Wimbledon in 1996, while Thomas Muster won his lone major at the 1995 French Open. Both are correctly classified as 'one-slam wonders.' Patrick Rafter won 2 US Opens (1997, 1998) and Yevgeny Kafelnikov won 2 majors (1996 French Open, 1999 Australian Open), so they are not one-slam players.

Goran Ivanišević reached four Wimbledon finals (1992, 1994, 1998, 2001), winning the championship in his final appearance in 2001. This makes option C correct. He was renowned for his powerful serve and is the only wild card to win Wimbledon in the Open Era.

In the 1999 Wimbledon final, Pete Sampras defeated Andre Agassi in straight sets (6-3, 6-4, 7-6). Therefore, Agassi won 0 sets and Sampras won 3 sets. The scoreline 0-3 represents Agassi's sets first, followed by Sampras's sets.
