EUGENE, Ore. - Brianne Theisen and Dakotah Keys posted first day personal-bests to take the lead of their respective Pac-12 combined events Saturday at Historic Hayward Field.

Theisen, in her first heptathlon in nearly two years, had a 107-point first day PR that included an all-conditions best in the 200 meters and a heptathlon PR in the high jump. She led with 3,758 points and was well ahead of second-place Keia Pinnick of Arizona State, who was at 3,402.

"I was extremely nervous today," said Theisen. "I was nervous and tense all day.

"I was extremely happy with the 200. The crowd helped a lot. I'm happy to be through today up 150 points on what I wanted to score. I think I will be much more relaxed tomorrow."

She opened the day by winning the 100 meter hurdles in 13.50. She then made five straight first-attempt clearances in the high jump, the last of which set a heptathlon personal best at 6-0/1.83m.

Theisen then just missed a PR in the shot put with a throw of 41-4.5/12.61m. The fifth-year senior from Humboldt, Sask., then wrapped up the day with her all-conditions PR in the 200 meters of 23.90.

Her point total surpassed her previous first day best, 3,651 from the 2010 Texas Relays, by nearly 100 points.

In the decathlon, Keys had a huge PR in the high jump to take the first day lead with 3,969 points. Marcus Nilsson was second with 3,887 points and Michael Bolligar of Washington State was third with 3,737 points. Oregon's Alec Fellows was seventh with 3,575 points.

Keys had three decathlon PR's, including a huge clearance in the high jump at 6-9/2.06m. That was an all-conditions personal best for the freshman from Sweet Home, Ore., and a decathlon PR by five inches. Keys also set decathlon bests in the 100 meters at 11.16 and the shot put at 42-2.25/12.86m.

"I feel like a couple of the events were not up to par, definitely not what I was hoping for, but still overall I am happy," said Keys.

He also went 23-7.5/7.20m in the long jump and ran 51.11 in the 400 meters.

Fellows, a freshman from Woodway, Wash., had a personal best in the 100 meters of 11.12 to highlight his day.
