Early in what would become a tight test of a U.S. Open final, Angelique Kerber sprinted forward to somehow reach a drop shot and scoop a down-the-line winner to a corner.
The Arthur Ashe Stadium crowd roared, and Kerber celebrated by raising her right hand and wagging her index finger in the air, as if to remind opponent Karolina Pliskova — and everyone else — "I'm No. 1!"
Yes, she is. And a two-time Grand Slam champion, too.
