Bladensburg and Sherwood, each of which came up a few points shy of winning Maryland state basketball titles last year, will be looking for different results this time around while defending champion Wootton hopes to repeat as state semifinal action gets under way tonight at Cole Field House.

Sherwood, a 64-62 loser to Frederick in the final a year ago, gained a slight measure of revenge with a 68-54 decision during the regular season. However, Sherwood Coach Mel Laughner is quick to point out that Frederick rebounder Mike Boyd (6-4 1/2) didn't play that night.

"He'll definitely make a difference inside, " said Laughner.

Frederick is led by Nike Boyd's brother, Donny, one of leading scorers in Maryland with a 23.0 average.

Sherwood relies on a balanced scoring attack and the leadership of 5-10 Tim Charles.
