US Open 2022 -- Numbers behind Venus and Serena Williams' remarkable careers as they team up for doubles

It's almost impossible imagine tennis without Venus and Serena Williams. The two sisters began their professional careers in 1994 and 1999, respectively, winning many majors and profoundly impacting the sport.

But as the saying goes, all good things must come to an end.

Serena announced in August via a first-person essay on Vogue.com that her playing career is winding down. She didn't use the word «retirement,» instead opting for «evolution» when describing her eventual exit from professional tennis. She said her desire to grow her family was a reason for walking away and suggested the 2022 US Open could be her final tournament.

Venus, however, hasn't revealed much about her tennis future. After losing to Belgium's Alison Van Uytvanck in the first round of the US Open, Venus said in a postmatch news conference that she is «just focused on the doubles,» where she will play with Serena.

On Thursday (7 p.m. ET on ESPN), the Williams sisters will face the Czech Republic's Linda Noskova and Lucie Hradecka in the first round of the doubles tournament. It's the first doubles night session at Arthur Ashe since Mike and Bob Bryan defeated Colin Fleming and Jonathan Marray in the men's doubles quarterfinals in 2013. It's also the first women's doubles night session there since the Williams sisters lost to Nadia Petrova and Maria Kirilenko in the third round in 2012.

If Serena and Venus lose, it could be the final doubles match they play together professionally. Regardless of the outcome, the Williams sisters' legacies as tennis legends are ironclad. And we have the stats to prove it.

Here are some numbers behind Venus' and Serena's Hall of Fame-worthy careers:
