PITTSBURGH - Pittsburgh coach Jaime Dixon said his team gave Bucknell plenty of respect - even before the Bison handed the 10th-ranked Panthers their first loss of the season.

"Our guys were well aware of how good they were coming in," Dixon said after Bucknell's shocking 69-66 win Sunday night. "It was one of those nights as far as how we played. But our defense is not where it needs to be."

Kevin Bettencourt made two free throws with 23 seconds remaining to give the Bison the lead, and Bucknell hung on to beat the highest-ranked opponent in school history. It was the Bison's second straight road upset - they defeated defending Atlantic 10 champion Saint Joseph's 69-62 on Tuesday.

"You don't play these games on your schedule without thinking you can come in and beat them," Bucknell coach Pat Flannery said. "I felt like we could come in and play with them. I'll put it in perspective when I calm down."

Chris McNaughton scored 17 points, Charles Lee had 14, including the last two free throws with 2.3 seconds left, and Bettencourt added 13 for Bucknell (9-4), which has won six straight. The last time the Bison won six consecutive non-conference games was 1958-59.

"It's a lot of fun to play a game like that," McNaughton said. "To end up winning, it's just tremendous for us. The way we played as a team made the difference."

Carl Krauser had 20 points for Pitt (10-1), which had a 48-game, home-winning streak against non-conference teams snapped.

"We were ready for the game, but when we got here, it was a different story," Krauser said. "They came out blazing and we didn't step up to the challenge as well as we should have. Everyone hates to lose a game like this. It's an eye-opener."

The last time Bucknell defeated Pittsburgh was Jan 11, 1975, when the Bison were coached by Jim Valvano. That was Bucknell's last victory over a current Big East team.

Chris Taft had 19 points for Pitt, which trailed by nine points at halftime. Freshman Ronald Ramon sparked a second-half comeback for Pitt, hitting consecutive 3-pointers to complete a 14-1 run and give the Panthers a 51-50 lead.

Bucknell held a four-point lead with 3:50 left, but Antonio Graves and Krauser hit 3-pointers to give Pitt a 64-62 lead with 2 minutes left.

Bettencourt converted a three-point play with 1:37 left to give Bucknell a 65-64 lead. Krauser answered with a basket on Pitt's next possession, putting the Panthers back on top, 66-65.

But Krauser had a layup blocked by Abe Badmus with 58 seconds left, and Graves was called for a foul away from the ball with 23 seconds remaining.

Bettencourt converted both free throws to give Bucknell a 67-66 lead.

"We did a great job of keeping our composure down the stretch," Bettencourt said.

On Pitt's next possession, Krauser slipped while trying to drive the lane and was called for traveling. But Pitt got the ball back with 13 seconds left when Bucknell turned it over on the inbounds pass.

Graves missed a 15-footer with 5 seconds left. Lee then made the two free throws, and Krauser's desperation shot at the buzzer bounced off the glass. It was Pitt's second loss in three seasons in the Petersen Events Center.

Bucknell was 14-of-16 from the free throw line, with Bettencourt going 9-of-10. Pitt was only 9-of-20 from the line.

Pitt was trying to complete its second consecutive unbeaten non-conference season. The Panthers went 14-0 in non-conference play last year and had won 25 consecutive non-league games since a Dec. 31, 2002, loss at Georgia.

In the first half, Bucknell scored 23 points off 15 turnovers in taking a 42-33 lead. It was the most first-half points allowed by the Panthers this season.

"That's embarrassing," said Taft, who had five turnovers. "I know that won't ever happen again."
