At 6-5, Azarenka raced to triple set point, but was too tentative on her chances while Collins pressed with aggressive forehands. Azarenka squandered four set points in total in that game, eventually losing serve with a woebegone drop shot attempt into the net.
Nevertheless, in the tiebreak, Azarenka took a 3-1 lead behind powerful groundstrokes, and maneuvered her way to a fifth set point at 6-4 when a strong serve was returned wide by Collins. On the next point, Azarenka finally clinched the set when a volley forced a long error by the American.
After powering through a protracted and tight first set, it was unfortunate for Azarenka when she began to exhibit signs of severe discomfort during the very first game of the second set. Collins claimed the initial game of the set, breaking serve with a stellar lob winner over the disheartened Azarenka.
After Collins held for 2-0 with a thumping backhand winner, Azarenka stepped to the line again, and fired three double faults in the game to drop serve once more and give Collins a 3-0 advantage. Azarenka received treatment after that game, but the pain was too great for her to keep playing, and the former World No.1 made the tearful decision to abandon the match.
