Sports Records and History

The Australian Open was played on grass courts at Kooyong until 1987. In 1988, it moved to Flinders Park (now Melbourne Park) and switched to hard courts (Rebound Ace, later Plexicushion, now GreenSet). Wimbledon has always been on grass and remains so. The US Open switched from grass to clay in 1975, then to hard courts in 1978.

Mats Wilander won the US Open on grass in 1983 (at the West Side Tennis Club) and then on hard court in 1988 (at the Flushing Meadows). This makes him the only male player to win the same Grand Slam tournament on two different surfaces. Nadal won French Open on clay/hardcourt, but not on grass.

Andre Agassi is the correct answer as he achieved the Career Golden Slam - winning all four Grand Slam titles (Australian Open, French Open, Wimbledon, US Open) plus an Olympic Gold Medal (1996). Pete Sampras, Rod Laver, and Arthur Ashe did not achieve this specific combination.

The question asks about the first match surface between Federer and Nadal with claimed answer 'hard court'. This is a specific historical fact about tennis that requires verification. Their first meeting was at Miami 2004, which was on hard court, so the claimed answer appears correct.

Federer's first career clay-court victory over Nadal came at the 2007 Hamburg Masters final, where he won 2-6, 6-2, 6-0. This victory ended Nadal's 81-match clay winning streak and remains Federer's only clay-court win against Nadal to date.

Federer defeated Nadal 6-4, 6-4 in the 2009 Madrid Masters final. This was a straight-sets victory for Federer on clay, making it one of his rare wins against Nadal on clay surfaces.

Federer won one set against Nadal at Roland Garros in 2005 (4-6), 2006 (1-6, 6-1), and 2007 (4-6). In 2008, Nadal won 6-1, 6-3, 6-0 without dropping a set. So 2005, 2006, and 2007 are the correct years.

The question asks to identify the odd one out among tennis players in relation to Federer. While all listed players are Federer's contemporaries and rivals, the question designates Djokovic as the distinguishing option.

Pete Sampras won his first Grand Slam title at the 1990 US Open, defeating Andre Agassi in the final. This victory launched his legendary career, during which he won 14 Grand Slam titles.

Novak Djokovic lost his first Grand Slam final at the 2007 US Open to Roger Federer. He won his first Grand Slam title at his next opportunity - the 2008 Australian Open, which was his second Grand Slam final.

In 2009, the ATP Masters 1000 series underwent changes. Hamburg was demoted to a 500-level event starting in 2009, while Madrid, Montreal, and Paris remained as Masters 1000 tournaments.

Theo Walcott broke Wayne Rooney's record as the youngest player to score a goal for England. Rooney scored his first England goal at 17 years and 317 days against Macedonia in 2003. Walcott surpassed this by scoring at 17 years and 75 days, making him the youngest ever. The record has since been broken by others.

As of 2009-2010 when the question's premise of 12 total Grand Slam titles was accurate, Serena had won 3 Wimbledon titles (2002, 2003, 2009). Her total at that point included 5 Australian Opens, 3 Wimbledon, 1 French Open, and 3 US Opens. The answer reflects her Wimbledon count during that specific period of her career.
