Pospisil retires following injury, Shapovalov advances
A matchup between two Canadians came to a premature end at the BNP Paribas Open in Indian Wells, Cali., Saturday.
Denis Shapovalov of Richmond Hill, Ont., advanced to the third round after Vancouver's Vasek Pospisil retired with an injury early in the first set.
Pospisil was trailing 2-0 when he appeared to hurt his lower back on a serve and took a medical time out.
He returned to the court after spending several minutes with a trainer but struggled with his serve and had seven double faults before bowing out with Shapovalov up 3-0.

Pospisil, 31, edged American J.J. Wolf 6-4, 4-6, 6-4 in a first-round match Thursday, but lost his cool in the second set and repeatedly smashed his racked on the court.
Fernandez, seeded 23rd in the tournament, is set to take on No. 9 seed Anastasia Pavlyuchenkova of Russia in the round of 32.
