Chelsea Gray couldn’t suppress her happiness after picking up her 10th assist of the game. And she couldn’t hide it after ward when she talked about matching Dawn Staley’s conference record with a second career triple-double.

‘‘I’m not surprised,’’ Duke coach Joanne McCallie said after Gray scored 18 points with 11 rebounds and 10 assists to lead No. 3 Duke to a 90-53 victory over Boston College on Sunday before 3,137 fans at Conte Forum. ‘‘She’ll be getting a lot more of those, I’m sure.’’
