Guard Brian Nunn scored 26 points, 22 in the first half, to lead Whitman to an easy 88-60 win over Walter Johnson in a Maryland Class AA Region II quarterfinal last night at Whitman.

The Vikings (13-8) will face Bethesda-Chevy Chase in the second round at 7 p.m. Thursday at B-CC, which won both games between the teams during the regular season. Walter Johnson, the defending Class B state champions, finished 10-13.

Whitman took advantage of poor Wildcats shooting in the first half and led at the break, 49-28.

The Vikings led only 25-18 with 5:43 left in the opening half when they began to dominate the game on both ends of the court. The Wildcats were unable to follow their numerous missed shots, and were also unable to stop the Vikings' fast break.

Nunn capped the ensuing 14-5 run with a layup, and Whitman led comfortably, 39-23.

A Will Hughes' three-point play pulled the Wildcats within 13, but that was as close as they'd get as Whitman broke the game open .

After Scott Morrow hit a driving eight-footer, Nunn, for the second time in less than a minute, scored an easy layup after a Wildcats miss. He then stole the ensuing inbounds pass for another easy layup.

"The coaches saw that they were all looking for the offensive boards, so they told me to fly," Nunn said. "That run really dejected them."

After Nunn's steal and layup, a pair of Kevin Beyer free throws put the Vikings up, 47-26, with 41 seconds left in the half.

Whitman led by as many as 24 early in the second half, but the Wildcats, led by guard Shane Brey, pulled to within 12. Brey, who led the Wildcats with 17 points, hit three three-pointers during an 18-6 run that cut the deficit to 61-49.
