Ray Emery started the first three games for Mason, who was out with an upper-body injury. Mason played the final 7:15 in a 4-1 loss Tuesday night.
Mason was just getting warmed up. He played perhaps his best game of the season, shutting down a Rangers team that pressured him with shots all game. He was a wall in the final tense minutes when the Rangers pulled goalie Henrik Lundqvist for the extra attacker.
