The Salem State pool became the domain of the Marblehead swim team on Wednesday as the Magicians dominated the Northeastern Conference championships at the O’Keefe Center.The Magician girls rolled to a comfortable, but expected, win over Beverly while the boys easily outdistanced Danvers to win the team combined title as well.”It was really terrific,” Marblehead coach Sue Guertin said. “We had a lot of kids (who) really came through.”The Magicians won only three individual events, but used their depth to steamroll the competition.In the girls competition, Katherine Foley won the 100 butterfly (1:03.27) and Marissa Spanos took the 50 free (29.23). The lone boys individual win came from Ted Millett in the 200 IM (2:00.22).”We had a lot of awesome swims by everyone,” Guertin said.Classical’s Katelyn Kidney won the 200 free (2:05.01) and Peter Rondeau took fourth in the 200 IM. Lynn English’s Langston Toxey was second in the boys 200 free and third in the 200 IM.
