TUCSON, ARIZ. ? For 20 minutes, Northern Arizona played the No. 1 team in the country close. Then the Arizona Wildcats turned up the pressure, and reality set in.

Will Bynum scored a career-high 18 points, all on 3-pointers, as Arizona routed the Lumberjacks 101-66 Wednesday night. The Wildcats outscored Northern Arizona 57-27 in the second half.

“I knew that was coming,” Lumberjacks coach Mike Adras said.

Jason Gardner scored 24, including five of six 3-pointers, and had five assists. The Lumberjacks committed 26 turnovers against the Wildcats’ trapping, full-court defense.

Freshman Hassan Adams added 21 points as five Arizona players reached double figures.

Luke Walton left the game with 15:42 to play in the first half with a sprained right ankle and did not return. The team trainer said the injury was in a different place than a sprain in the same ankle that sidelined Walton for the first exhibition game.

“It’s not a severe sprain,” coach Lute Olson said. “He should be fine by next week.”

Arizona (2-0) also didn’t have Salim Stoudamire, last year’s Pac-10 freshman of the year, who has yet to play this season because of a sprained left ankle. Stoudamire will return when Arizona plays its next game, at home against Saint Louis, on Tuesday.

Kelly Golob scored 14, including four of seven 3s, while Ryan McDade and Aaron Bond added 12 points each.

The Lumberjacks (1-2) of the Big Sky Conference, who were listed as 34-point underdogs by oddsmakers, trailed just 44-39 at the break.

“We did not have a good practice yesterday, and we played that way in the first half,” Olson said. “I think it will be a learning experience for them, that you’re going to play how you practice.”

At halftime, Olson and his assistants had a simple message.

“We suggested they play harder,” Olson said.

Arizona scored the first 13 points of the second half to go up 57-39 on Adams’ layup, which followed a Northern Arizona turnover.

Channing Frye’s 14-footer made it 61-41 with 15:32 to play. Golob’s two 3-pointers and one by Kyle Feuerbach cut it to 63-50 with 12:39 remaining. But Gardner’s three-point play and layup boosted the lead to 68-50.

“We know we are going to be everybody’s target,” Gardner said. “We didn’t come out like we wanted, but we got it done.”

Northern Arizona cut the lead to 70-56 on Bond’s stuff with 10:10 to go, then Arizona put it away with a 16-2 run, punctuated by Gardner’s final 3-pointer.

Arizona eased off its full-court defense in the final 10 minutes.

“I’d wait for the game where they’re actually doing that the entire ballgame,” Adras marveled, “and it may not happen.”

Kodiak Yazzie’s basket put Northern Arizona up for the last time, 29-28, with seven minutes left in the half. Arizona finally put together an 8-0 run to go up 36-29 on Rick Anderson’s two free throws with 5:07 left until halftime.

But the pesky Lumberjacks came back with an 8-2 spurt to cut the lead to 38-37 on Kyle Feuerbach’s dunk with 1:34 to go in the half. Gardner’s 3-pointer with 3 seconds left gave Arizona its five-point halftime lead.

Walk-on Fil Torres sank a 3-pointer at the final buzzer to put Arizona over the century mark and beat the 34-point spread. Olson was yelling at Torres not to shoot.

“That was in really poor taste,” Olson said of the 3-pointer. “He wasn’t listening to me. What that tells me is he doesn’t want to play the next three or four games.”

The Wildcats’ first two opponents ” Western Kentucky and Northern Arizona ” committed 54 turnovers against Arizona. The Wildcats won those games by a combined 208-124.

No. 5 Pitt 69, St. Francis, Pa. 46

Pittsburgh ” Brandin Knight had 10 points, nine assists and eight rebounds as Pittsburgh opened a 14-3 lead and lose it. Pitt (2-0) improved to 26-0 against St. Francis, which is located about 75 miles east of Pittsburgh. The Panthers also are 53-0 against Northeast Conference schools.

The smaller, slower Red Flash (1-1) didn’t break into double figures until 4:52 remained in the first half.

Erick Wills hit five 3-pointers and scored 17 points to lead St. Francis. Pitt shot 47.4 percent despite making only 5-of-21 3-pointers. The Panthers went 22-of-36 inside the 3-point line.

No. 11 Maryland 97, Citadel 49

College Park, Md. ” Drew Nicholas scored 17 of his career-high 28 points in the first half as Maryland built a 26-point lead and cruised past The Citadel.

It was the 86th consecutive non-conference home victory for the defending NCAA-champion Terrapins (2-0), who never trailed in extending their overall home winning streak to 20 ” four short of the school record.

Steve Blake had 13 points, five assists and five steals for the Terrapins, who forced 30 turnovers. Kevin Hammack scored 19 points for the Bulldogs (1-2), who have lost 32 straight to ACC opponents since beating Clemson in 1979.

Georgia Tech 83, No. 17 Georgia 77

Atlanta ” B.J. Elder shook off leg cramps to score 24 points to lead Georgia Tech past Georgia.

The Yellow Jackets (2-0) overcame a 14-point deficit in the first half to snap a three-game losing streak against Georgia (1-2).

With about 5 1/2 minutes to go, Jarvis Hayes hit a 3-pointer to put Georgia ahead 71-69. Elder, meanwhile, hobbled to the bench with cramps in his left thigh.
