Malden Catholic athletic director and hockey coach Chris Serino died Monday, according to associates. He was 63. He had been battling throat cancer. Serino guided the Lancers to the top of the Catholic Conference and to Super 8 titles two straight years. “It’s tough, he wasn’t in good shape for about a month,” said John McLean, who took over as coach while Serino was ailing last season. “He put up a good fight.” Serino was also a coach and athletic director at Merrimack College for seven years. He resigned from his position there in 2005 and took over at Malden Catholic. Serino was a three-sport Globe All-Scholastic in hockey, football, and baseball at Saugus High School.
