Tavi Thomas ended the Oakland Mills dream of a perfect season Thursday night. Thomas drilled a 3-pointer with nine seconds left that gave visiting Calvert a come-from-behind 69-67 victory over No. 6 Oakland Mills in the Class 2A South region championship. Oakland Mills entered the game as the only unbeaten public school team left in the state - for boys - and the Scorpions finished with a 24-1 record. Oakland Mills was trying to make the state final four for the first time in 12 years, and a state championship would have meant the Scorpions did it with a perfect record.

Six players scored, including 10 points by the forwards in the paint, and John Carroll took a 24-7 lead after the first quarter and a 34-13 lead at the break.

The Calvert Cliffs Nuclear Power Plant shut down one of its reactors Tuesday after employees at the southern Maryland facility detected problems with a control rod. Operators took the plant's Unit 1 reactor offline around 8:30 a.m. to replace one of the electrical coils connected to a control rod and test all the other control rods, said Kory Raftery, a spokesman for Calvert Cliffs. The move came after monitoring of the reactor picked up "electrical noise" in that control rod, a sign that part of the connection might have gone bad, he said.
