Ottawa: 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 Sunday.
Schnur was a late replacement for Denis Shapovalov, who withdrew from the opening singles match Sunday 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.
