2026 US Open: Two Major Upsets as Six Top-10 Seeds Eliminated in First Week

The decisive moment came at the 2026 US Open third round. Taylor Fritz, the No. 9 seed from the United States, sat in the locker room afterward, hands on his head, whispering, "I don't know how I let that happen today." That was the moment when Fritz led 2-0 but still lost to Francisco Cerundolo of Argentina. Just a few hours later, Flavio Cobolli, the No. 5 seed from Italy, also realized his collapse when he won the first-set tiebreak but then lost three straight sets: 3-6, 0-6, 3-6 to Alexander Blockx of Belgium. These two results meant six of the top ten men's seeds were eliminated in the first week.
