As far as baby steps go, the Bruins took a pretty good one in Joe Sacco’s first game as head coach on Thursday at the Garden. The B’s received a second-period power-play goal from Elias Lindholm (!) and then relied on Joonas Korpisalo (along with his friend the post) to snap a three-game losing streak,

Joonas Korpisalo stopped 21 shots, Elias Lindholm scored the game’s only goal, and the Boston Bruins beat the Utah Hockey Club 1-0 on Thursday night in their first game since the team fired coach Jim Montgomery and named Joe Sacco as interim coach.
