Danielle Collins scripted a fine comeback win to battle past fellow American Katie Volynets 4-6, 7-6(3), 6-0 to secure a place in the Austin Open quarterfinals.
The 22-year-old Volynets dashed the hopes of 21-year-old South Korean lucky loser Sohyun Park, racing to a quick 6-1, 6-2 in a one-sided quarter-final match at the iconic CCI courts on Friday afternoon.
