In every season there are college basketball games that demonstrate the ultimate in athletic ability and precision execution, leaving fans wanting more. Last night's Arizona-Oregon game was not one of them.

No. 13 UA's 81-63 win over the Ducks was quite the opposite - two teams engaged in a painful (for the 14,337 at McKale Center) process of trying to find some sort of rhythm.

In the end, UA's defensive pressure, ability to rebound and a little lift from Jason Terry proved too much for the Ducks (13-12 overall, 6-8 in the Pacific 10 Conference).

The Wildcats (20-5, 9-4) achieved their ninth-consecutive 20-win season by forcing Oregon into a season-low 29.1 percent field-goal percentage, including a pitiful 16.7 percent performace (4-for-24) from 3-point range.

"We worked hard on getting out on their perimeter guys," said forward Corey Williams, who with six rebounds and 17 points was one of five Wildcats with five or more rebounds. "They didn't shoot it as well as they did up there."

Williams was referring to McArthur Court in Eugene, Ore., where the Ducks hit 47.4 percent (9-19) of their 3-pointers in a 70-65 UA win Jan. 27. While the Ducks were not setting the nets on fire with their shooting, the Wildcats were not helping themselves either. UA shot 43.1 percent and committed 17 turnovers. Arizona also could not seem to find a way to knock the Ducks out of the game, although keeping them at arm's length proved to be just as effective as Oregon was not able to mount any sort of comeback. The Ducks were able to cut a 40-24 halftime deficit to under 10 points just once in the second half, at 43-34 with 15 minutes to go.

"We didn't play as well as we wanted," forward Ben Davis said, who with 15 points and 13 rebounds had his 10th double-double in 14 Pac-10 games. "They hung around, but they were still behind by 10. It's okay to hang around if they're down by 10."

Davis also showed some restraint. After picking up his second foul just 1 minute, 41 seconds into the game, the senior - who leads the conference with 9.4 rebounds a game - played the rest of the first half, and the rest of the game (28 minutes in all) without drawing another one.

While Davis toned down, Terry heated things up with a career- and game-high 18 points on 7-10 shooting. Included in his repertoire against the Ducks was a pair of 3-pointers, another one-handed slam and numerous drives to the basket that he finished.

"Terry gave us a great lift coming in off the bench," UA head coach Lute Olson said. "He did a good job shooting and making things happen on both ends."

The freshman's play had such an effect on the crowd that twice in the second half, McKale's electronic billboards flashed "Terry for President."

"They're trying to put pressure on me," Terry said, joking about the nomination. Then, withdrawing his hat from the ring, he added, "I'm just a freshman, I've got three more years here."

Michael Dickerson rounded out the four Wildcats in double figures with 14 points and six rebounds.

UA totaled 49 rebounds, one more than Oregon. In Eugene, the Wildcats were outrebounded 36-33.

Duck Jamal Lawrence, who blitzed UA for 34 points last time, was held to just 14, all of them coming in the second half. Jamar Curry and Terik Brown added 12 and 11 points, respectively.
