Oliver gave the Flyers their biggest lead at 77-63 on a layup with 2:51 left and the deficit was too much for the Cardinal to overcome.

Johnson was scoreless and it was a one-possession game with less than three minutes remaining when Shepard made a ball-handling miscue and T.J. McConnell (11 points) made the steal with Johnson cashing in with a layup to give Arizona a 56-51 lead. He added a 3-pointer with 1:50 left and followed up with the first two of his free throws to boost the lead to eight and the Aztecs never got closer than three the rest of the way.

The Bears’ athleticism was expected to cause problems for the Badgers, but Baylor shot only 31.6 percent from the field, including 2-of-15 from 3-point range, and was outrebounded 39-33.

Baylor scored the game’s first basket and held the lead for 36 seconds until Kaminsky’s layup evened the score for the final time as Wisconsin suffocated the Bears in the first half, holding them to 20 percent shooting in the opening 20 minutes en route to a 29-16 advantage at the break. Kaminsky had 10 points and four blocks in the first half and added a three-point play early in the second half as the Badgers continued to pour it on.
