This year’s IIHF Men’s World Championship does not start until Friday, however Team USA is already getting ready for the event.  Team USA played a pre-tournament exhibition game with Germany on Sunday at SAP Arena Mannheim in Mannheim, Germany.  Three Bruins are on Team USA’s roster in forward James Hagens, forward Alex Steeves, and defenseman Mason Lohrei. Steeves was a late addition to the roster while Hagens and Lohrei were on the original preliminary roster. Hagens and Steeves both played in the exhibition with Hagens at center on the second line and Steeves at left wing on the third line. Lohrei did not participate in the contest.  Steeves had a multi-point outing. In the exhibition, he tallied one goal and one assist for two points to help lift Team USA over Team Germany 5-2. And that's game! The U.S. tops Germany 5-2 in its #MensWorlds exhibition game. Up next 👉 Switzerland for game one of the tournament on Friday, May 15.…
