DETROIT, Mich. -- Zach Hyman broke a 1-1 tie with the game-winning power-play goal early in the third period, and Steve Racine made a season-high 40 saves to lead Michigan to a 2-1 win against No. 5 Michigan Tech in a semifinal contest in the 50th Great Lakes Invitational at Joe Louis Arena.

Cutler Martin also scored for the Wolverines, who made several key defensive plays in the closing minutes to seal the win.

Hyman scored the go-ahead goal after Boo Nieves drew a power play for Michigan at the start of the third period. Nieves threaded the Michigan Tech defense for a chance in front that Michigan Tech goaltender Jamie Phillips (19 saves) turned away, but Nieves was hooked on the play by Mark Auk to put the Wolverines on the power play at 2:22.

On the man advantage, Hyman gave Michigan the lead for good with Michigan Tech in the midst of a personnel change. With the puck in the neutral zone, Michael Downing quickly fed Andrew Copp, who gained the zone and found Hyman in the slot. Hyman fired a long wrist shot into the top left corner of the net at 3:44 to give the Wolverines the lead.

Racine came up with a big stop at 11:20, as C.J. Eick drove to the net from the corner and tried to cut to his backhand. But Racine interrupted the play with his goal stick and covered the puck to stop play.

The Wolverines struck first in the first period after a great shift in Michigan Tech's zone. Copp had two jam attempts at the start of the shift, and eventually Hyman fed Cutler Martin at the left point. Martin's long slapshot beat Phillips on the blocker side to put the Wolverines up 1-0 at 6:28.

The Huskies tied it up four minutes later on a nice passing play, as Alex Petan dug the puck out of the corner to Tanner Kero, who fed cross-ice to Malcom Gould on a 2-on-1 down low. Gould beat Racine between the pads at 10:28 to tie the game up.

Racine made an outstanding save late in the period to keep it tied at the break. With 3:29 left in the first period, Kero pounced on a loose puck in the slot, but Racine made a sweeping glove save, his best of 16 in the period.

Racine was sharp again on Michigan Tech's second power-play chance of the night with Dexter Dancs in the box for slashing midway through the second period. He made his best stop, a blocker save on Tyler Heinonen's chance from the high slot at the 12:00 mark, to help the Wolverines kill off the penalty.
