A scary thought for the competition.

“I don’t know if I’ve peaked yet,” Serena Williams said in advance of this week’s Rogers Cup women’s tournament in Toronto, where she is the top seed. “I don’t know if I’ve gotten to the top of the mountain yet.

“If I’m there, I want to stay there.”

Williams is there, as she been throughout much of her career.

Perhaps the only question is, for how long? A few more months? A few more years? Forever?

With Serena, sometimes it feels that way, like like she’ll never stop winning, like time is her only true competitor.
