By Annie Maroon/DFP Staff Agganis Arena was quiet on Friday, with even the student sections largely empty, and that lack of energy was mirrored on the ice for much of the game as the No. 13/15 Boston University men’s hockey team lost 3-0 to the No. 12 University of Massachusetts-Lowell. “The fans were here. They would have energized us if we energized them,” BU coach Jack Parker said. “We didn’t get a goal. We’re down 2-0, but we could have been winning eight in a row and if you’re down 2-0 and you’re not doing anything, creating enough offense, it doesn’t energize.” Freshman goalie Matt O’Connor stopped 24 of 27 River Hawk (17-9-2, 12-7-2) shots, but the Terrier (14-13-2, 11-8-2 Hockey East) offense mustered just 25 on UML rookie goalie Connor Hellebuyck, few of them threatening. “I don’t think he saw a lot of Grade-A shots,” Parker said of Hellebuyck. “They played really well on the initial rush and really well covering out front.” BU had not been shut out in conference play since Nov. 6, 2009, against Northeastern University. The Terriers and River Hawks are now tied for fifth in Hockey East entering Saturday’s game in Lowell. After an uneventful first period, UML’s Scott Wilson put the River Hawks on the board a little over five minutes into the second. UML held the puck in the Terriers’ zone for most of a shift. Then BU’s forwards changed with the puck at their defensive blue line, and their defensemen, junior Garrett Noonan and freshman Matt Grzelcyk, couldn’t get off. Wilson came onto the ice and lifted a wrist shot over O’Connor without meeting much resistance from BU. “We never should have changed when the puck is at our blue line,” Parker said. “But either way, [Scott Wilson] really ripped it. That was a rocket.”
