For two years, Tim Thomas has been one of the best goalies in the world. For two games, Braden Holtby has matched him save for save. Making just his second NHL postseason appearance, Holtby stopped 43 shots Saturday to lead the Washington Capitals to a 2-1 victory over the Boston Bruins. One game after the Bruins opened the playoffs with a single-overtime victory, Nicklas Backstrom scored 2:56 into the second overtime to help the Capitals tie the defending Stanley Cup champions at one game apiece.
