Roll over, Nadal

One of the most amazing tennis matches you'll ever see just went down at the U.S. Open. An 18-year-old Spaniard, Carlos Alcaraz, defeated the third seed, Stefanos Tsitsipas of Greece, in a fifth-set tiebreaker. The match was stunning from start to finish.

The battle went on for more than four hours. The teenager was remarkably clever with his shots, and he never looked anywhere near tired. Tsitsipas sported his usual Odysseus look and played his usual strong game, but Alcaraz just kept coming at him, and the kid was stronger in the end. He never flinched. The New York crowd went nuts.
