WORCESTER – The Marblehead hockey team’s storybook run through the state tournament came to a halt on Thursday at the DCU Center.The Headers, surprising champs of Division 3 North, ran into a juggernaut in the defending Division 3 state champion, Scituate.The Sailors jumped out to a 4-1 first-period lead and put it on cruise control en route to an 8-2 win, led by a Dan Galvin hat trick, that sends them back to the TD BankNorth Garden on Sunday.It marks the fourth straight season that Scituate has played for the Division 3 title. And this one will have even more emotion, as the Sailors lost one of their own, Tim Mahoney, in a fatal car accident midway through the season.”We knew that we couldn’t underestimate Marblehead,” Scituate coach Mike Breen said. “I told the guys that we had to come out and take it to them in the first period because we couldn’t let them hang around with how good their goaltender (Aaron Reny) is.”Evidently, Breen’s team heeded his advice.Simply put, Scituate was just a bit too fast and talented for the Headers. The Sailors had plenty of quality scoring chances despite taking several ill-timed penalties in the game.And it was that fact that Marblehead coach Bob Jackson looked back at afterwards.”Scituate is a good team, a really good team,” Jackson said. “We knew they were good and they played like that.”The Sailors certainly came out playing like they wanted a return trip to Boston as Scituate put immense pressure on Reny right from the outset as the Headers (14-11-0) suffered from a case of stage fright in the early going.And it would take only 3:39 for that pressure to pay off as Brad Stenbeck crashed the net and slammed home a Kevin Lyons rebound for a 1-0 lead.Just under two minutes later, the Sailors doubled their margin when defenseman Pat Mahoney hit Galvin with a home-run pass at the Marblehead line. Galvin rushed in and put a backhander on Reny that broke off his pads and trickled across the goal line for 2-0 lead.”We were a little bit awestruck in the first 4:00,” Jackson said. “And unfortunately the young guys were the culprits for a couple of goals.”The Headers, meanwhile, could get nothing started offensively against Scituate’s Jamie Murray. Marblehead would go nearly half the period before getting its first shot on goal.Just short of the 8:00 mark, Galvin was in the right place at the right time when the Headers turned the puck over in the defensive zone. Galvin scooped up the loose puck in the high slot and beat Reny clean on a backhander on a partial breakaway.Just 23 seconds later, things got even worse for the Headers when Mac Luciani took the puck in the Scituate end and bolted nearly the length of the ice before unleashing a rocket from the top of the right circle that sailed over a frustrated Reny’s shoulder for a 4-0 lead jut 8:17 in.Jackson went to his bench, replacing Reny with backup goalie Tony Cuzner and the move seemed to work as the Sailors took back-to-back penalties 28 seconds apart to give the Headers a 1:02 5-on-3 advantage.Marblehead made Scituate pay for the mistakes when sophomore Anders Gundersen picked up a loose puck at the side of the net and shoveled it into a wide-open net, assisted by Andrew Bates and Mike Cohn, at 9:51.On the goal, Scituate’s Mahoney was called for cross-checking, giving Marblehead even more 5-on-3 time. But in a sign of things to come, the Headers couldn’t convert on their golden chance and the Sailors headed into the locker room with their 4-1 lead.Despite his team playing a dominant first period, Breen knew that the lead probably wasn’t big enough.”I didn’t feel comfortable at all with that margin,” Breen said.In the second, the Headers would be given a number of opportunities to make a game of this one as Breen’s uneasiness proved to be right on the money.For the third time in the contest, the Headers got a 5-on-3 power play when Mahoney and Galvin were sent to the box 34 seconds apart early in the second.Unlike its previous 2-man chance, M
