Brandt Clarke scored on a breakaway with 27 seconds left in overtime for his first career goal and the Los Angeles Kings rallied to beat the slumping Boston Bruins 5-4 on Saturday. Clarke had just been sprung from the penalty box for taking down David Pastrnak and was all alone when he skated in on Linus Ullmark and slipped the puck past the Boston goaltender. “My heart was racing for a while in the penalty box, and I think from when I touched it at the red line to when everyone was jumping on me, I don’t even really remember that section but that was pretty wild,” said Clarke, who was mobbed by teammates celebrating both his first-ever goal in 17 NHL games and the comeback by the Kings.
