MADISON, Wis. (AP) -- No one was more surprised at Joe Krabbenhoft's career-high 15 points than Bo Ryan.

"How many did he have? Did he really?" the Wisconsin coach said. "No wonder they had him over there to interview him after the game on the Big Ten Network. I was wondering what Joe was doing there."

Krabbenhoft scored 11 of his 15 in the second half and helped spark a 12-0 run, lifting Wisconsin over Wisconsin-Green Bay 77-57 on Saturday night to keep the Badgers undefeated against the Phoenix.

Krabbenhoft's performance was quiet everywhere else but the court. The senior forward didn't come to the interview room after the game.

"He let it come to him for the most part, he didn't force stuff and he was strong with the ball. That's how Joe can play," Ryan said. "I'm not saying he can get 15 every night, but there are nights that it can happen, because evidently it did."

Wisconsin (8-2) has won 15 straight over Green Bay (6-3).

Marcus Landry scored 14 points, Jason Bohannon 12 and Tim Jarmusz 11 for Wisconsin, which also got 11 rebounds from Keaton Nankivil.

"It's something the coaches told me to work on, and today happened to be the day the ball was falling into my hands," Nankivil said. "It doesn't really matter who gets the boards as long as we get them. Today they just kept coming off toward my part of the floor."

Mike Schachtner led the Phoenix with 21 points and Ryan Tillema added 10. Troy Cotton, who leads the Phoenix averaging 14.5 points per game, only managed five.

"I was kind of forcing some shots," said Schachtner, who went 6-of-13 from the field and 8-of-8 from the free-throw line. "I should have been kicking out a little more. That's just kind of the way it goes sometimes. I've just got to try to get other guys going too."

Since Ryan became coach of the Badgers, Wisconsin has always won the in-state rivalry by at least 10 points. Wisconsin took a 14-point lead early in the second half before the Phoenix went on a 9-0 run to whittle the lead to 52-47.

"We had some opportunities to go down three, didn't make some plays and they went on a big run on us. We just didn't respond to it," Phoenix coach Tod Kowalczyk said.

Instead, Wisconsin answered with a bigger run.

Landry hit a jumper and Krabbenhoft scored seven of the next 10 points in a 12-0 run to put the game out of reach and snap Green Bay's six-game winning streak.

"We just came out and really got aggressive defensively," Landry said. "We were able to pull away."

Said Schachtner: "When they went on a run, we kind of went our separate ways and that really hurt us."

But Green Bay squandered plenty of opportunities early, too.

In the first half, Bohannon twice crossed up Cotton, getting him to slip on the ground for one jumper, then hitting one with Cotton's hand in his face on the next possession to cap an 8-0 run that gave Wisconsin a 27-21 lead.

Schachtner kept it close by hitting a 3-pointer and four free throws in the waning minutes of the first half, but Jarmusz and Trevon Hughes hit 3s and Hughes added another jumper to give Wisconsin a 39-32 lead at halftime.

"We're down 31-30 and made some mental mistakes defensively, gave up two 3s to end the half and go down by seven at halftime instead of getting a stop and maybe taking a lead at halftime," said Kowalczyk, who fell to 0-7 against Wisconsin. "We just won six games in a row, and we've been defending really well with great ball pressure getting out and denying. I don't think we took Wisconsin out of their offense enough tonight."
