"Our team took a little while to adjust to the greens today," said head coach Ria Scott. "We worked on it after our round and are excited to get back out there tomorrow."
Isagawa is currently tied for third on the leaderboard after carding her eighth at or below par round of the season. The reigning two-time All-Pac 12 was one of just seven players to break par on the day, carding a 1-under round (70).
After making bogey on the opening fifth hole, Isagawa played the next 14 holes at 3-under with three birdies and 11 pars. The Wailuku, Hawaii, native gave two strokes back before closing with a birdie on the par-three, 146 yard fourth hole.
Freshman Cathleen Santoso carded a 74 (+3), Oregon's second-best round of the day, and is tied for 17th. Santoso sat at even par through 15 holes, but slipped with three straight bogeys to close her round. Santoso made birdies on the 11th hole and was one of just two players in the field to birdie the par-four second hole.
Freshman Marcella Pranovia also fired a quality round, shooting a 75 (+4). Pranovia is tied for 26th place on the leaderboard. The Bali, Indonesia, native had just three pars in her first 10 holes before finding her groove. Pranovia played holes No. 17 through 5 at 1-under par to rebound.
Junior Cali Hipp shot a 77 (+6) and provided Oregon's final counting score. She made 10 pars on the round and birdied the par-four 18th hole. Hipp is currently tied for 42nd place. Sophomore Caroline Inglis carded a 78 (+7) with birdies on holes No. 14 and 16.
"We played some good golf in stretches," said Scott. "Everyone hit some good shots out there. We just need to put it all together for tomorrow. Their preparation has been great."
Sunday's final round will tee off with a shotgun start at 9 a.m. (PT) on the Stanford Golf Course. The Ducks will tee off between holes No. 6 and 10 and are paired with No. 42 Denver and UC Irvine.
