The Islanders remained perfect in the second game of back-to-back sets as they edged the Wild, 2-1, on Sunday afternoon at Barclays Center.
The Metropolitan Division-leading Islanders (33-16-6), who have won three straight and are 9-1-2 since Jan. 13, are 9-0-0 in the back end of back-to-backs.
Thomas Greiss made 26 saves in his fifth straight start of allowing one or fewer goals. Devan Dubnyk stopped 32 shots for the Wild (27-24-5).
The Wild, too, were playing on back-to-back afternoons after a 4-2 win at New Jersey on Saturday.
But the Islanders looked fresher from the starter, pressuring early in the first period and finally taking a 1-0 lead at 14:05 as Valtteri Filppula, along the right boards in the offensive zone, sprung a wide-open Anthony Beauvillier to the crease with a backhanded feed.
