DiPietro stopped 37 shots in Saturday's 5-4 overtime win over Chicago.
The visitors out-shot the Bruins 28-13 through two periods, but DiPietro kept things tied up until a wild third period that saw the teams trade two-goal bursts. The 27-year-old then got rewarded for his efforts when Elias Lindholm potted the winner in OT. DiPietro has won three straight starts as Jeremy Swayman's backup, allowing six goals on 97 shots (.959 save percentage) during his winning streak.
