The Belarusian converted seven of her 12 break point opportunities to advance to the second round, where she will face fifth-seeded Donna Vekic of Croatia. American Danielle Collins came out ahead in a marathon 6-4 5-7 6-2 battle with China’s Zhang Shuai on a sun-soaked afternoon on the campus of San Jose State University. The rising 25-year-old University of Virginia product said her conditioning was the difference in her first-round match. “I think I did a really great job making it physical,” Collins said. “I’ve been working a lot on my fitness the last couple weeks after Wimbledon. I’ve had a good couple weeks of training and I think it paid off today.” Collins will next face Zheng Saisai after the Chinese defeated Britton Heather Watson 6-3 6-1 in their first-round match.
