The Hopkinton High School boys hockey team’s bid for an upset in the state tournament came up short Wednesday night with a 5-4 overtime loss to host Masconomet at Valley Forum in Haverhill.

Hopkinton led 3-1 after the first period and 4-2 after two, but Masconomet scored twice late in the third period to force the extra session.

The 18th-seeded Hillers, champions of the Tri-Valley League Large School Division, end their season with a record of 14-5-2.

Masconomet (14-7), seeded 15th, advances to play Canton in the Sweet 16.
