Canadians Heather Bansley and Brandie Wilkerson, ranked No. 16, won 22-24, 21-18, 15-13 after being down a set and 10-4 in the second.
“We made more than enough opportunities for ourselves to win,” Claes said. “Fought through that first, up in the end and we let them back in. Everybody is good out here so letting that door open just a little and here we are, we lost.”
