FP – Australian pair Karrie Webb and Minjee Lee had mixed fortunes in the second round of the LPGA Tour’s Portland Classic on Friday but are well behind impressive Canadian teenager Brooke Henderson.

Henderson drained birdies on three of her final four holes to fire a 67 and move to 11-under overall, one shot ahead of Germany’s Caroline Masson at the midway point of the tournament at the Columbia Edgewater Country Club course.

West Australian Lee, 19, started the day three shots off the pace but a topsy-turvy even-par 72 – a round that included four birdies on the front nine and four bogeys on the back – dropped her down the scoresheets to sit tied for 30th at four-under.

Webb was the opposite, a much-improved 68 following her opening-round 72 to be at two-under.

But the day belonged to 17-year-old Henderson, who finished in the top five in two major championships this season.

“I had to stay patient,” Henderson said.

“I knew I was hitting great shots. About the fourth hole on my back nine I said, ‘Let’s go make some birdies,’ and I was able to do that.

“It is a great position to be in, but it is a long way from being over and I still have a lot of work to do.”

The 17-year-old rising star on the LPGA Tour only made it into the field via a Monday qualifier.

Candie Kung of Taiwan, Jenny Shin of South Korea and Julieta Granada of Paraguay were tied for third at nine-under. Kung shot a 66, Shin a 68 and Granada a 69.

First-round leaders Amy Anderson and Sandra Changkija finished with par 72s and are in a tie for ninth.

Of the other Australians, Sarah Jane Smith (71) and Stacey Keating (75) made the cut at even-par, but Katherine Kirk (72) and Sarah Kemp (73) won’t be there for the weekend.
