NEW YORK (AP) -- Serena Williams isn't sure if she's willing or able to reach 22 Grand Slam titles.

Still, she knows her next goal is 19 after she won her 18th on Sunday at the U.S. Open to match Chris Evert and Martina Navratilova. And should she get to 19, she figures she'll then want 20.

If she keeps playing the way she did in Flushing Meadows, maybe Steffi Graf's Open-era record of 22 will start to sound realistic.

It was an unusual scene after a major sports event late Sunday night: Williams and the player she defeated in the final, Caroline Wozniacki, were celebrating together. Wozniacki took over her good friend Williams' phone and was posting photos to Instagram with singer Joe Jonas and model Gigi Hadid.
