- Italy's Camila Giorgi upset four-time champion Caroline Wozniacki 6-4, 6-2 on Wednesday to reach the quarter-finals of the WTA Connecticut Open, a final US Open warm-up hardcourt event.
Giorgi dispatched the former world number one in 78 minutes to book a last-eight date with Spain's Garbine Muguruza, who eliminated Chinese qualifier Peng Shuai 6-2, 3-6, 6-3 in another second-round match.
Giorgi, ranked 38th, also ousted Wozniacki in last year's US Open but lost their only other meeting this year at Eastbourne.
"I knew I was going to get limited break chances and when I did get them, I didn't convert," Wozniacki said. "I knew I had to be aggressive out there and try to push her back, but I didn't manage to do that. She played well and I didn't."
