NEW YORK, New York -- Milos Raonic advanced to the second round of the U.S. Open, but fellow Canadian Vasek Pospisil missed a chance to join him after what he called a "clear mistake from the umpire."
Pospisil was left fuming Tuesday after a 4-6, 3-6, 7-6 (9), 6-2, 7-6 (10) loss to Brazilian qualifier Rogerio Dutra.
With the fifth-set tiebreaker tied 10-10, the umpire overruled a linesperson's call on Dutra's shot that was initially ruled long. That gave Dutra match point, which he then converted to complete the win over the native of Vernon, B.C.
"It was a clear mistake, a huge mistake," Pospisil said. "That ball was 2-3 inches long. There was no doubt -- the next thing he called it in. Something has to be done about mistakes like that.
"To overrule on the baseline is absolutely terrible. The linesperson called it out, it was not even close. I was in a state of shock and anger. I've never experienced a call like that, especially at this stage of a grand slam match.
"It doesn't excuse that I didn't convert leading to that point, but I would have had another match point and maybe I would have gotten it."
The match was completed after being delayed by rain Monday night with Pospisil up two sets to one, but trailing the fourth set 4-0.
"In the third set I had stopped serving well, I had nothing in my legs and I could feel my body going downhill," he said. "I had cramps but I felt better today."
The 10th-seeded Raonic from Thornhill, Ont., had a lot less drama in his opener as he defeated Italian qualifier Thomas Fabbiano 6-3, 7-6 (6), 6-3.
"I know he's very capable, I remember him from juniors," Raonic said of Fabbiano.
In the women's draw, Aleksandra Wozniak of Blainville, Que., reached the second round with a win over Serbia's Vesna Dolonc 7-5, 7-6 (7-5).
