Arizona's Brandon Ashley absorbs contact as he gets tangled up with Oregon State forward Jarmal Reid at Gill Coliseum in 2015. The Wildcats have never swept the Oregon trip under Sean Miller.
On Sean Miller’s seventh try, after MoMo Jones carried the Wildcats to a three-overtime victory at Cal back in 2010-11, the UA coach finally broke through with his first Pac-12 road sweep.
As Miller points out often, they aren’t easy to get.
Especially the one the Wildcats will take this week.
Arizona has become by far the Pac-12’s best road team since the conference expanded to 12 teams, winning 65.6 percent of its Pac-12 road games. But the Wildcats have recorded two-game sweeps just 13 times over 35 trips since Miller became the UA’s head coach in 2009-10.

That’s right: Even the Derrick Williams-led team of 2010-11 couldn’t win at Oregon State. The 2013-14 Elite Eight Wildcats lost at Oregon, where last season’s Wildcats were drilled 85-58.
