Not to be outdone, Brianne Theisen, Kimber Mattox and English Gardner impressed on the track for the top-ranked Women of Oregon, while the No. 13 men saw a number of personal and seasonal bests, including freshman Johnathan Cabral in the hurdles, Dior Mathis in the 100 meters, Sam Crouser in the javelin and Tim Costin in the steeplechase.
"Everything happens at the end of the season and has been building a crescendo," said Associate Athletic Director Vin Lananna. "Since the Pepsi Invitational it's been a huge training phase for everyone one, hopefully we're ready going into the last few meets.
"I think Pac-12's will be competitive on both sides. We have to fire at all cylinders, you'll see cool things from starts to finish."
As the sun broke through the clouds for the afternoon, Summers capped the college section with one of the highlights of the meet. The freshman from Estacada, Ore., had a first attempt clearance at 6-0/1.83m. That mark was tied for the fifth-best clearance in the NCAA this season, and also ranked fourth in school history.
"It was on my first attempt, and it was clean," said Summers, who had to survive a third attempt clearance at 5-10.75 to get a shot at 6-0. "It's been a goal of mine since my freshman year of high school.
"I'm usually not one to freak out after clearing a big jump, but I freaked out. I was going crazy. There's still potential for a better mark. Six feet is a big barrier for a lot of jumpers, but I'm passed it, and I think I have room for improvement."
Summers became just the fourth Duck to clear 6-0 outdoors, joining Camille Jampolsky (6-2.75), Theisen (6-1.25) and Laurel Roberts (6-0.5).
Newson had a remarkable series in her first-ever triple jump. The senior from Richmond, Calif., opened at 39-8.5/12.10m and then improved to 40-11/12.48m on her third attempt before a final attempt jump of 41-5.25/12.63m. That mark ranked as the third-best in school history.
"It was my first time ever doing the triple jump," said Newson. "I had no expectations, but it was a lot of fun.
"This year I am used to things. I'm getting faster. I want to focus on triple jump and mix things up."
Schaudt set personal bests on three consecutive attempts to win the long jump. The senior from Philomath, Ore., opened at 24-1/7.34m, had a slight improvement to 24-1.75/7.36m on his second attempt and then soared to a personal best 24-4.5/7.43m on his third and final jump.
"I'm pretty happy with the way things went," said Schaudt. "I only took three jumps, but all three were personal records."
Clark, from North Bend, Ore., set an outdoor personal best in the pole vault with a clearance at 13-5.25/4.10m. That moved her into a tie for sixth all-time at Oregon.
Theisen, the two-time NCAA heptathlon champion, continued to show her versatility. One night after setting a personal best in the 200 meters at 23.99, the senior from Humboldt, Sask., was a surprise winner in the women's 400 meters in 53.72. That was an all-conditions personal best and ranked tenth on the UO career list.
"It was my first time running out of blocks since sophomore year, so I'm happy I earned a personal record," said Theisen. "I am ready for the heptathlon. I was disappointed last year, and I've been chomping at the bit to get out there for two years."
Gardner won her first outdoor 100 meters of 2012 in a wind-aided 11.28. That was the eighth-fastest time in the nation for the sophomore from Voorhees, N.J.
"It was okay," said Gardner. "It was my first 100 of the season. I can't ask for more. I came out with a good time."
Mattox got the day off to a solid start by running a :09 personal best in the women's 3,000 meter steeplechase. The senior from Bend, Ore., put on a big charge over the final 800 meters to finish second in 10:06.58. Lauren Johnson of Nike won in 10:04.49. Mattox's time was the fourth-fastest time in the NCAA this season, and was the third-fastest in school history.
"I feel good," said Mattox. "It was nice to have people out here pulling me along. I was able to take a few seconds off my time."
The Ducks swept the short hurdles. Cabral won the men's 110 hurdles in 13.83, while senior Lyndsay Pearson took the women's 100 hurdles in 14.18.
Those two runners came back to sweep the 400 meter hurdles. Pearson won the women's race in 1:00.86, while Cabral captured the men's competition in a personal-best 52.78.
"We've done some strength training and technique," said Cabral. "But I stay focused and do what I can do best."
Mathis, a sophomore from Detroit, Mich., ran his fastest 100 meters as a Duck to win in 10.65.
"I knew I was going to win right away, I had a great takeoff," said Mathis. "I felt good for limited practice because of football. It's difficult to balance both sports in college, but I've done it before."
Crouser, a freshman from Gresham, Ore., had a best throw of 243-8/74.27m to win the men's javelin.
Austin Ourderkirk was the winner of the men's pole vault. The junior from Newport, Ore., cleared 16-4.75/5.00m.
Laura Bobek won the women's shot put. The sophomore from Astoria, Ore., won at 45-10.75/13.99m.
The women's 800 saw an incredibly close finish with Nike's Sara Vaughn getting to the line first in 2:05.29, followed by Oregon's Anne Kesselring in 2:05.54 and Laura Roseler in 2:05.84. The Ducks' Becca Friday was fourth in 2:06.47.
In one of the more understated performances from Saturday, Costin ran a :07 PR in a runner-up finish in the men's 3,000 meter steeplechase. The sophomore from Springfield, Ore., timed 9:07.01.
The Ducks swept all four relays. The women won the 4x100 in 44.78 and the 4x400 in 3:46.20. The men took the 4x100 in 40.90 and the 4x400 in 3:15.06.
