Jin Young Ko sits atop the leaderboard at -8 after the first two rounds of the Cambia Portland Classic.

The No. 2 ranked Ko recorded six birdies and one bogey, shooting a 5-under 67 on Friday to secure the lead. She now holds a one-stroke advantage over Gemma Dryburgh heading into Round 3 at the Oregon Golf Club.

“I did a great job first two rounds and this course is not easy, so fairways and greens are really narrow so I had to focus on my shot,” said Ko.

After heavy overnight storms and more rain forecasted for Saturday, the Portland Classic announced that third-round play would be canceled.

“We will determine whether the event will be played over 54 or 72 holes prior to beginning play on Sunday,” the tournament said in a statement.

The Portland Classic also stated that play might be scheduled for Monday to complete the 54 or 72 holes.
