In the men’s bracket, top seed Zach Foushee (West Linn, Ore.) fell in the round of 16 to 2013 Pacific Northwest Golf Association (PNGA) Mid-Amateur champion Matt Hartley (Vancouver, Wash.) 4 and 3. Hartley, the 16th-seed, tallied four birdies in his round, including three on the front nine, where he shot 32. Hartley will play 24-seed Clayton Madey (West Linn, Ore.), who defeated Kurt Simmons (Hermiston, Ore.) 4 and 2.

Second-seed Thomas Lim (Moorpark, Calif.) used a strong back nine to hold off Conner Barr (Beaverton, Ore.) 2 and 1 and advance to the quarterfinals. Lim, last year’s runner-up, will play 26-seed Sulman Raza (Eugene, Ore.), his teammate at the University of Oregon. Raza advanced by beating John-Michael Pilot (Vancouver, Wash.) 4 and 3.

Thirty-seed Brett Johnson (Vancouver, Wash.) defeated Ryan Melnychuk (Grants Pass, Ore.) 2 and 1 to move on to the quarterfinals. Earlier in the day, Johnson got past the third-seed, Justin Kadin (Corvallis, Ore.) 4 and 3. Johnson will play six-seed Brian Jung (Corvallis, Ore.), who defeated Noah Yano (Lake Oswego, Ore.) 4 and 2 in the round of 16.

The final matchup of the quarterfinals for the men will be 20-seed Austin Landis (Gladstone, Ore.) against 21-seed Taylor Schmidt (Boise, Idaho). Landis defeated Oregon State’s Kevin Murphy (Rogue River, Ore.) 2 and 1 in the round of 16. Murphy was the four-seed in the tournament. Schmidt advanced after winning 4 and 2 against Justin Wiles (Klamath Falls, Ore.)

In the women’s bracket, both top seeds advanced to the quarterfinals. Defending champion Kendall Prince (Wilsonville, Ore.) defeated Juhee Lee (Wilsonville, Ore.) 3 and 2 and will play Oregon State’s Ashlee Pickerell (Salem, Ore.) tomorrow morning. Pickerell beat Haleigh Krause (Eugene, Ore.) 1-up. The two seed in the tournament, Monica Vaughn (Reedsport, Ore.), moved on by defeating Kaitlyn Oster (Portland, Ore.) 1-up. Vaughn will play Brenna Murphy (Corvallis, Ore.) in the quarterfinals.

The biggest upset of the day in the women’s bracket was 14th-seed Sunshine Powers (Portland, Ore.) advancing and eliminating the Championship’s three-seed, Caroline Inglis (Eugene, Ore.) 2 and 1. Powers will play another double-digit seed in 11th-seed Cali Hipp (Caldwell, Idaho). Hipp defeated 2013 Oregon Women’s Stroke Play champion Aram Choi (Portland, Ore.) 2 and 1.

The final quarterfinal matchup in the women’s division will be last year's runner-up Gigi Stoll (Tigard, Ore.) playing Rosie Cook (Bend, Ore.). Cook played in one of the most competitive matches of the day, when she beat Krissy Peterson (Canby, Ore.) 1-up. The two players halved just two holes all day, and Cook was up by as much as three on the front nine, while Peterson came back and was 2-up with seven holes to play before Cook won on the last hole. Stoll defeated Aaren Ziegler (Canby, Ore.) 2 and 1 in the round of 16.

Quarterfinal matches begin tomorrow at the OGA Golf Course at 8:00 AM, while the semifinals start at 1:20 PM.
