SEATTLE -- Even while winning its first 12 games, the Colorado women's basketball team knew it wasn't perfect and that a loss could come at any time.
That loss came Thursday night, as Washington knocked off the Buffs 75-67 at Alaska Airlines Arena.
"This is really the first time I've seen just a lack of focus, and Washington is good enough to take advantage of that," CU head coach Linda Lappe said on KVCU 1190 AM radio after the game. "We had too many mental lapses at crucial parts of the game. In close games and in games on the road in the Pac-12, those are going to kill you."
Colorado (12-1, 1-1 Pac-12) had started 12-0 for just the third time in school history, but couldn't get the job done in the second half against the Huskies (9-4, 1-2), who rode the hot hand of Jazmine Davis.
A freshman from San Jose, Calif., Davis scored 21 of her game-high and career-high 27 points after intermission for the Huskies.
CU was yielding just 51.8 points per game before Thursday. Washington was the first team to score more than 66 and the first to hit at least 40 percent of its shots (finishing at 45 percent) against the Buffs this season.
"We stopped defending," Lappe said. "I don't know that we ever really defended tonight. We made some mistakes personnel-wise a couple times and just didn't quite have the focus that we needed to win that game on the defensive end."
Chucky Jeffery led Colorado with 20 points -- including the 900th of her career -- while Julie Seabrook matched her career-high with 18 and Brittany Wilson had 10.
The CU offense hit just 30.8 percent of its shots after intermission and went 8 minutes, 25 seconds without a field goal during one stretch of the second half.
"Offensively, I thought we just took some rushed, hurried, forced shots tonight that I hadn't seen in a long time, and we did it for too many minutes," Lappe said.
That lack of discipline on offense hurt the CU defense.
"They had a lot of momentum," said Jeffery, who added seven rebounds, six steals and four assists. "We were taking some quick and bad shots, so we were playing 30 seconds on defense, and coming down and taking a bad shot and then coming back and playing 30 more seconds on defense. It was just draining us."
Like it has in every game, CU took the lead into halftime, 37-35. But, Washington opened the second half on a 10-2 run, with Davis scoring seven of those points.
The Buffs regained the lead with a 12-2 run, but Washington countered with a 12-2 run of its own.
CU took its last lead at 57-55, just before Davis drained back-to-back 3-pointers.
Another set of back-to-back buckets from Davis gave Washington its biggest lead, at 67-59.
CU's Lexy Kresl then hit a 3-pointer with 1:58 to go, snapping the long field-goal drought, but the Buffs made just two of its last 12 field-goal attempts as Washington hung on.
"It's time to regroup," said Jeffery, whose team will visit Washington State on Saturday. "We don't have time to dwell on a loss or a win. We have to get our team back to focus. That's what we lacked a lot tonight. We weren't focused. We let down mentally in a lot of parts of the game."
CU's loss leaves just five undefeated teams in the country: No.1 Baylor, No. 5 Maryland, No. 8 Ohio State, No. 13 Texas Tech and No. 17 Green Bay. ... Jeffery now has 902 career points.
