Jahmyl Telfort had a game-high 18 points and Alexander Nwagha recorded his first career double-double, but a 15-2 Princeton run late in the second half erased a nine-point lead for the Northeastern men’s basketball team (1-5) and gave the Tigers (4-2) the victory in the championship game of the London Basketball Classic on Saturday afternoon at the Copper Box Arena, 56-54.
