OSIJEK, Croatia — Canada's Daniel Nestor and Vasek Pospisil lost their doubles match at the Davis Cup Saturday, handing Croatia a 2-1 lead in the best-of-five World Group tie. Toronto's Nestor and Vancouver's Pospisil started strong, taking a two-set lead and going up a break in the third before Croatia's Marin Cilic and Ivan Dodig stormed back to win 2-6, 3-6, 6-4, 7-5, 6-2. That leaves 18-year-old Denis Shapovalov in a must-win situation Sunday against Borna Coric.
