NEW YORK — Serena Williams can call it "evolving" or "retiring" or whatever she wants. And she can be coy about whether or not this U.S. Open will actually mark the end of her playing days. Those 23 Grand Slam titles earned that right.

If she keeps playing like this, who knows how long this farewell will last?
