Colorado set a team record for blocks (26) and Lauren Schaefer recorded her first career double-double Wednesday night, yet the Buffaloes still fell to Iowa State in volleyball 3-2.

Colorado (5-13, 0-10) has lost 10 straight matches dating back to Sept. 12.

Now with eight different five-game losses under the Buffs' belt, it's becoming routine for Colorado to fall in the fifth game.

In this version, the Buffs were defeated 24-30, 30-24, 25-30, 30-19, 15-13.

"Part of it, I think, is just getting confidence," coach Pi'i Aiu said. "Right now, the kids are shaking. We've got to find some confidence, regardless of who we're playing."

Schaefer said that entering the fifth game she was confident her team would pull off the victory.

"It's frustrating because out on the court, it felt like we were going to win. There was no doubt in my mind," said Schaefer, who had 13 kills and 12 blocks. "I think it comes down to — especially in the fifth game — minimizing the errors."

Colorado handled Iowa State (10-10, 3-7) in the first game 30-24. The Buffs outblocked Iowa State 5.5 to one while hitting .286.

The second game was a different story.

Leading 10-9, Iowa State went on a run that included three Lauren Cummings kills and increased the Cyclones lead to 21-14. Though the Buffs fought back to make it 24-20, they just dug themselves into too big of a hole and lost 30-24.

Colorado won eight of the final 12 points in the third game, prevailing 30-25.

But the Buffs again got comfortable and gave away the fourth game, 30-19.

"I think it's frustrating when we go out and win the first game, then go out in the second game and slack off," junior Alex Buth said. "And then in the third game, we decide to come out (and play hard). Then the fourth game it's the same (pattern)."

Buth, who had a team-high 15 kills while also recording 11 digs and eight blocks, said the team is getting close to finishing out a match.

"We really need to start believing in ourselves, and I think that will get us a win," Buth said. "It's just right there in our hands — it's just so close — and we're letting it fall every time."

Aiu said it comes down to playing better in crunch time.

"We've got to play a little bit better when the game's on the line — from the first touch of the ball to the termination," Aiu said.

Erin Boeve played outstanding for the Cyclones, recording a game-high 19 kills while also chipping in 13 blocks and eight digs. Lauren Cummings also contributed for Iowa State, tallying 16 kills and 10 blocks.

Colorado starts the second half of its conference schedule on Saturday at Baylor (10-10, 3-7), and Schaefer said the team isn't going to let its record affect its play.

"We've stopped talking about our record," Schaefer said. "We have plenty of season left to go, and I think it would be really sad if we wasted it away."

When asked if he's spoken to his team about the 10-game losing streak, Aiu said, "I don't know anything about any (losing) streak."
