Vanecek turned aside 20 of 22 shots during Sunday's 2-1 preseason loss to New Jersey.
Vanecek got the starting nod during the Islanders' preseason opener and defended the road crease for the entire game. He put forth a decent performance and should compete with Semyon Varlamov for the No. 2 goaltending job behind Ilya Sorokin as the preseason rolls on. Vanecek made 22 regular-season appearances for Utah last year, going 5-13-3 with a 2.94 GAA and .883 save percentage.
