Carlos Alcaraz became the world's youngest No. 1 tennis player after beating Casper Ruud at the U.S. Sunday-open.
At 19, the Spaniard is the only male teenager to top the Pepperstone ATP Rankings; women have had younger tour leaders for decades.
Alcaraz beat Ruud in the U.S. on Sunday. Open final 6-4, 2-6, 7-6, 6-3. Either player, rated third and fifth, would have been No. 1.
Rafael Nadal and Novak Djokovic, both nearing retirement, dominated men's tennis.
Alcaraz won a third-set tiebreaker to go up 2-1, then won the fourth to serve for the title. He won with an ace.

"I'll never forget this day," he said.
Before Frances Tiafoe eliminated Nadal in the fourth round, the top place was his.
Alcaraz overcame Tiafoe in a long semifinal to reach No. 1.
Alcaraz's rise during Nadal's dominance means the teenager is doing his part to keep Spain dominant, including modelling his arsenal after Nadal's.
Nadal won the French Open as a teenager in 2005, the latest to do so. Juan Carlos Ferrero, a former No. 1 and Nadal challenger, is Alcaraz's coach.
Alcaraz's Nadal-like toolbox, mental coolness, muscular physicality, and ton-plus groundstroke balls put him in Arthur Ashe Stadium on Sunday and on the Tiffany & Co. trophy.
Ruud said after the match, "Today was amazing for Carlos and I." "It's fun that both finalists are No. 2 and No. 1. No. 2 isn't horrible."
