Ko, bidding to become the youngest winner of a major championship, will start the final round four shots off the lead after posting a 1-under-par 69 on Saturday.
Ko, who is playing with an ailing left wrist, will be 17 years 3 months and 24 days old on Sunday. Young Tom Morris is the youngest winner in major championship history. He was 17 years 5 months and 8 days old when he won the British Open in 1868. A Ko victory could also make her the youngest world No. 1 in the history of pro golf. If she wins, she will move to No. 1 in the Rolex world rankings as long as Stacy Lewis finishes T-2 or worse. Lewis will begin Sunday tied for 22nd, nine shots off the lead.
“It’s going to definitely take a low one,” Ko said of her chances to win.
How is the pain in Ko’s left wrist?
“My wrist is feeling better,” Ko said. “I can still feel it, but I mean as long as it doesn't get worse . . . I’ve got to just kind of ice it.”
