Rittich allowed one goal on 24 shots during Sunday's 2-1 preseason win over the Islanders.
Rittich defended the home crease against his former team during the Devils' preseason opener, and he performed admirably while playing the entire game. Across 30 regular-season appearances with the Islanders last year, he went 14-10-3 with a 2.76 GAA and .894 save percentage. He'll presumably compete with Jake Allen for work in the crease early in the 2026-27 regular season.
