Coquitlam, British Columbia: Lydia Ko showed playing partner Stacy Lewis a lot more than a great golf swing in the 15-year-old's historic Canadian Women's Open victory.
"I was most impressed with just her demeanor," Lewis said. "I mean you would have never known that it was the final round of an LPGA event. She played like she had been there before."
Ko became the youngest winner in LPGA Tour history and the circuit's fifth amateur champion Sunday, closing with a 5-under 67 for a three-stroke victory over Inbee Park.
