Fred Perry
Fred Perry was an English tennis and table tennis player and former World No. 1 who won 10 Majors including eight Grand Slams and two Pro Slams single titles, as well as six Major doubles titles. He also won three consecutive Wimbledon Championships and was the World Amateur number one tennis player from 1934 to 1936. Before Andy Murray came along in 2013, Perry was the last British player to win the men’s Wimbledon championship, in 1936, and the last British player to win a men’s singles Grand Slam title until Andy Murray won the 2012 US Open. All of this without any enhancing drug assistance!
Andy Roddick
Good ol’ Andy became a Grand Slam singles champion when he won the title back at the 2003 US Open, defeating Juan Carlos Ferrero in the final. Roddick is the most recent North American male player to win a Grand Slam singles event, the most recent to reach the top ranking, and the most recent to claim the year-end world No. 1 (2003). He reached four other Grand Slam finals (Wimbledon in 2004, 2005, and 2009, and the US Open in 2006), losing to Roger Federer every time though; the pair had a rivalry from 2001 until 2012. He ranked in the top 10 for 9 consecutive years between 2002 and 2010 and won five Masters Series in that period. He still remains one of the only players in the Grand Slam era to have remained so highly ranked and to have reached more than three grand slam finals and only won one major.
