Two weeks ago, the US Open stole the attention away from Wimbledon by announcing a star-studded Mixed Doubles competition. Alcaraz is paired with Emma Raducanu, and Zheng teamed up with Jack Draper (maybe fellow British stars Raducanu and Draper should team up instead).

Alcaraz already is 5-0 in Grand Slam finals, which includes going 2-0 at the French Open — which he won three weeks ago via a comeback from two sets down against No. 1 Jannik Sinner in the final — and 1-0 at the U.S. Open.

Despite the jaw-dropping figure, it still fails to top Serena Williams' 2003 NetPro signed patch rookie card, which sold for $266,400 in 2024. Alcaraz is known for his ability to succeed and adapt across all three playing surfaces.
