Carlos Alcaraz Garfia (born 5 May 2003) is a Spanish professional tennis player. He has been ranked as high as world No. 1 in men's singles by the Association of Tennis Professionals (ATP), and is the current world No. 3.
Alcaraz has won 15 ATP Tour-level singles titles, including four major titles and five Masters 1000 titles. Following his win at the 2022 US Open, Alcaraz became the youngest man and the first male teenager in the Open Era to top the singles rankings, at 19 years, 4 months, and 6 days old.
Alcaraz began his professional career in 2018 aged 15, going on to win three titles on the ITF Men's World Tennis Tour and four on the ATP Challenger Tour. He broke into the top 100 in rankings in May 2021, and ended that year in the top 35 after reaching his first major quarterfinal at the US Open. In March 2022, Alcaraz won his first Masters 1000 title at the Miami Open at the age of 18, and then won his second at the Madrid Open where he defeated Rafael Nadal, Novak Djokovic, and Alexander Zverev in succession. In late 2022, Alcaraz won his first major singles title at the US Open. Finishing the year as the youngest year-end No. 1 in ATP ranking history, he was later named the Laureus World Breakthrough of the Year for his performance in the season.
In 2023, Alcaraz claimed two additional Masters 1000 titles at Indian Wells and Madrid, and earned his second major title at the Wimbledon Championships, defeating Djokovic in an epic final. In 2024, he won his third major title at the French Open, and went on to successfully defend his Wimbledon title, defeating Djokovic again to become the youngest man in the Open Era to complete the Channel Slam.
