PORTLAND, Ore. (AP) — The end of an amazing streak came suddenly and unexpectedly when world No. 1 Jin Young Ko missed a par putt from inside 3 feet on the ninth hole at Columbia Edgewater.
Until that surprising miss, Ko had played 114 consecutive holes without making a bogey, a record run of blemish-free golf. She finished at 4-under-par 68 in the opening round of the Portland Classic, four shots off the lead.
Mi Jung Hur and Hannah Green each shot 8-under 64 to share the top spot. Jane Park and 18-year-old Monday qualifier Yealimi Noh were one shot back.
Ko, who went bogey-free over 72 holes and shot 26 under to win the CP Women's Open by five shots last week, began with four straight pars before a three-hole stretch an eagle and two birdies. She missed a 3-foot par putt on the par-4 ninth hole, her only blemish of the day.
"I did 114 holes and then done. It's cool," Ko said. "So I want to do again, 115 holes bogey-free round hopefully. But yeah, I'm free."
The South Korean, a four-time winner this year, including two major championships, had not made a bogey since early in the third round of the Women's British Open, where she finished third. Her streak eclipsed Tiger Woods' PGA Tour record of 110 bogey-free holes, set in 2000. It's also the longest known bogey-free streak in LPGA Tour history.
Ko was proud of her achievement, but the run was wearing on her.
"I can focus more on my shot and don't even think about, oh, bogey, bogey, no," she said. "Now I can more focus for tomorrow."
Defending champion Marina Alex was at 2 under.
Juli Inkster, captain of the U.S. Solheim Cup team, is playing for the 31st time in the 72-hole tournament that started in 1972 and is the tour's longest running non-major event. Inskster, who won in Portland in 1992, shot 75.
Joanna Klatten made a hole-in-one on the 167-yard 13th hole.
