Canadian qualifier Duncan Chan falls in National Bank Open first round

MONTREAL — Canadian qualifier Duncan Chan exited the National Bank Open with a first-round loss to Thiago Agustin Tirante of Argentina on Tuesday afternoon.

Chan, ranked 601st in the world, fell 6-3, 1-6, 7-6 (3) in two hours one minute at IGA Stadium after upsetting No. 90 Hugo Gaston of France to qualify for the men’s singles main draw at the ATP Masters 1000 event.
