In honor of reigning Wimbledon champion Andy Murray's 27th birthday today, we look back at the Scottish tennis star's first big win on the world stage. In 2004, after starting play on the Challenger Tour the previous year, the then-17-year-old took home his first major trophy when he won the boys' title at the US Open. Seeded third, Murray beat Sergiy Stakhovsky 6-4, 6-2 in the final. After the match, Murray thanked his mom, Judy, for "making lots of noise." That same year, Roger Federer beat Lleyton Hewitt in the men's final to claim his fourth Grand Slam title and his first of five straight in New York. Murray went on to represent Great Britain later that month in the Davis Cup, and, by 2005, he had cracked the Top 100 in the world rankings. Telling the BBC shortly after his win at Flushing Meadows that he hoped to one day make the world top 10, Murray has since won the US Open (2012), an Olympic gold medal (2012), Wimbledon (2013) and a slew of other tournaments. He is ranked No. 8 in the world -- after reaching a career-high No. 2 in 2009 -- and is playing in the Italian Open this week.
