Louisville, KY (SportsNetwork.com) - It wasn't a pretty win, but Kentucky stayed undefeated all the same.

Thanks in part to 13 points from Aaron Harrison along with 11 points and 11 rebounds from Trey Lyles, the top-seeded Wildcats posted a 64-51 victory over Cincinnati in a third round matchup of the NCAA Tournament Midwest Region.

The Wildcats (36-0) struggled shooting the ball for much of the first half, and the upset-minded Bearcats were able to keep things close over the first several minutes of the second half.

Kentucky, though, ultimately pulled away to advance to next week's Sweet 16, where it will face either West Virginia or Maryland in Cleveland.

Troy Caupain had 13 points and Shaq Thomas gave 10 points and five rebounds for the eighth-seeded Bearcats (23-11), who had edged Purdue by one point in overtime on Thursday to advance in their 29th NCAA Tournament appearance.
