BIRMINGHAM, Great Britain – When Serena Williams was asked about young Madison Keys’ prospects in 2015, the World No.1 did not hesitate.

“I think she can go really, really far; I think that she can be the best in the world. The way she played today, I definitely think she has the potential to be No.1 and win Grand Slams.”

Now, almost a year and a half later, Keys is one step closer to fulfilling Serena’s prediction: by virtue of her win over Carla Suárez Navarro to reach the final of the Aegon Classic Birmingham, Madison Keys will move into the WTA Top 10 on Monday.

Keys’ milestone comes as no surprise for fans who’ve followed her career: she currently sits at No.16 and has been threatening a breakthrough all year long. She’s fresh off of a career-best clay court season that saw her reach her first final on the red clay of the Internazionali BNL d’Italia and make the second week of the French Open, and earlier this year, she made the quarterfinals at the Miami Open. Keys has four Top 20 wins so far this year, too.

Now, Keys adds her name to an elite group of American women who have made their mark on WTA history.

Americans To Debut In WTA Top 10 (Last 25 Years):
Lindsay Davenport (1994)
Chanda Rubin (1996)
Venus Williams (1998)
Serena Williams (1999)
Madison Keys (2016)

There have been 118 different players who have achieved a Top 10 ranking since the WTA Rankings were introduced on November 3, 1975, and 27 of those have been Americans. Keys is the first American to make her Top 10 debut since Serena did so 17 years ago on April 5, 1999.

But that’s not all – with Serena and Venus Williams already there, this will be the first time since September 2005 that there are three Americans in the WTA Top 10. Back then, Davenport was ranked No.2 with Venus and Serena at No.7 and No.9, respectively.
