Arizona opened up as large as a 17-point lead, but Oregon State hung in there before the Wildcats finally won their first-round game of the Pac-10 Tournament 78-69 on Thursday afternoon.
Derrick Williams led Arizona with 22 points and seven rebounds, while also hitting five of his six three-point attempts.
Kevin Parrom and Lamont Jones finished with 13 points each and Solomon Hill led the game with 12 rebounds, five of which were offensive.
Oregon State shot 50 percent from the field and suffered due to its performance at the line, where it went 6-16.
Jared Cunningham had 23 points, but 19 came in the first half. In the second half, Cunningham struggled with cramps and was never able to get going.
Arizona turned the ball over 16 times and once again struggled with the numerous defenses of Oregon State before finally settling in and pulling away.
Oregon State cut the lead to 58-51 on an Ahmad Starks three-pointer, but the UA proceeded to go on a 10-0 run to make it 68-51.
With the win, the Wildcats advance to play USC on Friday, as the Trojans defeated Cal in the opening game on Thursday.
