Miller won his 373rd game, moving past Andy Moog for sole possession of 17th place on the career wins list. He also moved within one victory of tying John Vanbiesbrouck for the most by a U.S.-born goalie.
Miller stopped Victor Hedman's first-period rebound with this left arm while prone on the ice, and turned aside Brayden Point's shot on a breakaway in the second.
Ritchie swatted home a knee-high puck after Pontus Aberg's power-play shot went off the glass and wound up in from of the crease at 4:51 of the third.
Point skated down the slot and got his 18th goal of the season off a pass from behind the net by Nikita Kucherov, tying it at 1-all with 1:26 left in the second.
