Isner broke twice in the first set and used his strong serve to capitalize on the advantage. The American hit 10 aces and won 46% of his return points
John Isner beat Canada’s Brayden Schnur 6-1, 6-4 in 66 minutes to give the United States an early 1-0 lead at the ATP Cup on January 2.
Schnur was a late replacement for Denis Shapovalov, who withdrew from the opening singles match on January 2 due to fatigue. The Canadian is recovering from having contracted COVID-19 at a recent tournament in the Middle East.
Isner saved the only break point he faced.
