As things stand, the former leads the head-to-head 2-1. Their very first encounter came in the quarterfinals of the 2023 US Open. Here, it was Shelton who emerged victorious after four entertaining sets. The younger of the two Americans furthered his head-to-head lead by defeating Tiafoe in three sets in the final of last year's ATP 250 clay event in Houston. Their latest meeting though, a third-round clash at the 2024 US Open, went the older American's way. Finding himself two-sets-to-one down, the 27-year-old mounted a spirited comeback at Flushing Meadows, as he won the fourth and fifth sets 6-4, 6-3 respectively, to oust Shelton from the hardcourt Major.Interestingly, the Americans had paired up to play men's doubles at the 2025 Mubadala Citi DC Open in Washington, but they faltered in the very first round as they lost to Australian doubles specialists John Peers and Matthew Ebden.
