Retired American tennis player Andy Roddick took to Twitter to show his support for fellow American and tennis icon, Serena Williams, as she made it through to the third round of the 2022 US Open.

Roddick decided to retire from the game in 2012 following ongoing struggles with a shoulder injury and to also shift his focus to a foundation that he started, called the Andy Roddick Foundation. The Grand Slam winner celebrated his 40th birthday this past Tuesday.

The American tweeted that he has known Serena Williams since they were small kids and that she's always been a "bad**s".

Williams managed to progress to the third round of the competition after defeating second-seeded Anett Kontaveit 7-6(7), 2-6, 6-2. The 23-time Grand Slam winner will be hoping to end her illustrious career in style as she aims for a record-equalling (with Margaret Court) 24th title in what will be her last ever Major tournament.

The 40-year-old former World No. 1 will face talented Aussie Ajla Tomljanovic in the third round of the US Open on Friday.
