A tough weekend for Ashleigh Buhai saw her finish in a share of 57th in the LPGA Tour’s Standard Portland Classic at Columbia Edgewater Country Club in Portland, Oregon.

After opening with a superb six-under-par 66 on the first day, which put her just a shot off the first-round lead, and following it up with a four-under 68 to move to 10-under through halfway, still just one off the lead, Buhai closed with three-over 75 and four-over 76 in the third and fourth rounds.

Buhai slipped to three-under for the tournament in a disappointing end to the week.

Akie Iwai of Japan joined her twin sister Chisato as a rookie LPGA Tour winner, closing with a six-under 66 for a four-stroke victory. Akie Iwai capped the bogey-free round with birdies on the final two holes, running in an 18-footer on the last before Chisato rushed on the green and sprayed her with champagne. The 23-year-old Japanese player broke through in her first season on the LPGA Tour after winning six times on the JLPGA Tour.
