The Arizona Wildcats (4) are all of a sudden under pressure atop the Pac-12 as they visit the Utah Utes just one win ahead of the second place UCLA.

Since opening their season 21-0, Arizona has lost two of four and had a close call in a 67-65 over Oregon. They have undoubtedly missed Brandon Ashley, who will miss the rest of the season with a foot injury, as he was hurt during the loss to Cal.

A loss would mean three straight on the road for Arizona, who then have to play Colorado on the road Saturday, a team that is just two wins behind Arizona in the Pac-12. Wildcats coach Sean Miller said his team will have to find new ways to score without Ashley, who was contributing 11.7 points per game.

"We've had so many games this year where we didn't make our free throws, we didn't shoot the ball well or sometimes didn't have a lot of attempts from (3-point range)," Miller told reporters, according to ESPN. "The combination of our defense and (rebounding) have allowed us to be 23-2, not 15-10. Nobody knows more than I that the ball going in the basket a little bit more will give us a lot more room for error down the stretch."

The positive for Arizona is their defense has not suffered and they have only allowed two teams this year to crack the 70-point mark, but none as recently as Jan. 9. Arizona's next three opponents after Utah (Colorado, Cal and Stanford) are all in the mix for the Pac-12 lead as the regular season winds down.

Utah lost to Arizona on the Wildcats' home court and now the Utes have a chance to return the favor. At 4.5 games out, Utah is unlikely to threaten anyone for the conference lead, but a strong finish to their season could certainly earn them a bid to the NCAA Tournament.
