Postava posted an 18-save shutout in AHL Grand Rapids' 5-0 win over Rockford on Wednesday.
Postava earned his third shutout of the campaign. He's up to 14-6-0 with a 1.77 GAA and a .935 save percentage, showing that he can keep pace with prospect goalie Sebastian Cossa. Postava was recently with the Red Wings as a backup while Cam Talbot (undisclosed) was ailing, but Postava still has some developing to do before challenging for an NHL job.
