Lindsey Caroline Vonn (née Kildow; born October 18, 1984) is an American alpine ski racer with the U.S. Ski Team. She has won four overall World Cup championships – one of only two female skiers to do so, along with Annemarie Moser-Pröll – with three consecutive titles in 2008, 2009 and 2010, plus another in 2012. Vonn won the gold medal in downhill at the 2010 Winter Olympics, the first ever in the event for an American woman. She has also won five consecutive World Cup season titles in the downhill discipline, four consecutive titles in Super G, and three consecutive titles in the combined as of 2012.

Vonn is one of five women to have won World Cup races in all five disciplines of alpine skiing – downhill, super G, giant slalom, slalom, and super combined – and has won 53 World Cup races in her career as of March 14, 2012. Only two women have more World Cup victories in their careers, Austrian Annemarie Moser-Pröll with 62 and Swiss Vreni Schneider with 55, both retired from active racing. With her Olympic gold and bronze medals, two World Championship gold medals in 2009 (plus three silver medals in 2007 / 2011), and four overall World Cup titles, Vonn has become the most successful American skier in the history of alpine skiing.

Roger Federer (German pronunciation: [ˈfeːdəʁɐ]) (born 8 August 1981) is a Swiss professional tennis player who held the ATP No. 1 position for a record 237 consecutive weeks from 2 February 2004 to 18 August 2008. Federer has occupied the #1 ranking for 285 overall weeks, one week short of the record 286 weeks held by Pete Sampras. As of 28 May 2012, he is ranked World No. 3. Federer has won a men's record 16 Grand Slam singles titles. He is one of seven male players to capture the career Grand Slam and one of three (with Andre Agassi and Rafael Nadal) to do so on three different surfaces (clay, grass, and hard courts). He is the only male player in tennis history to have reached the title match of each Grand Slam tournament at least five times and also the final at each of the nine ATP Masters 1000 Tournaments. Many sports analysts, tennis critics, and former and current players consider Federer to be the greatest tennis player of all time.

Federer has appeared in an unprecedented 23 career Grand Slam tournament finals, including a men's record ten in a row, and appeared in 18 of 19 finals from the 2005 Wimbledon Championships through the 2010 Australian Open, the lone exception being the 2008 Australian Open. He holds the record of reaching the semifinals or better of 23 consecutive Grand Slam tournaments over five and a half years, from the 2004 Wimbledon Championships through the 2010 Australian Open. At the 2012 Australian Open, he reached a record 31st consecutive Grand Slam quarterfinal. During the course of his run at the 2012 French Open in Roland Garros, Federer eclipsed Jimmy Connors long standing record of 233 match wins in Grand Slam tournaments when he defeated Adrian Ungur in a second round match.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
