ONE37pm Looks Back at Serena Williams's 5 Best US Open Matches

Williams won her first major title in 1999 after knocking off Martina Hingis, who was ranked number one in the world at that time.

This win kickstarted an incredible career for Williams as a 17-year-old champion.

Victoria Azarenka and Williams had built up quite a regular occurrence of meetings in 2013.

Despite losing just a few weeks prior in a US Open tune-up, Williams came away with a decisive victory in three sets.

Williams made her way into the US Open final again in 2014, but she faced a different opponent this time.

This final was genuinely historic for Williams, who defeated Caroline Wozniacki, giving Williams her 18th major title, pulling her level with Chris Evert and Martina Navratilova.

Williams and her sister, Venus, earned their first of two doubles titles together at the 1999 US Open.

This sparked an amazing run that saw the duo win 14 majors together as doubles partners.

The 2002 US Open final marked the third straight major that Serena defeated Venus to hoist a championship.

The pair won doubles together in New York that year, but all the spotlight was on Serena. This win also helped give Serena the ability to continue her streak into the following year's Australian Open, which she won.

That created the 'Serena Slam' after she became the fifth woman ever to hold all four major titles at the same time.
