Shesterkin recorded the win after replacing Alexandar Georgiev to begin the third period of Sunday's 5-4 victory over the Sabres, turning aside all four shots he faced.
The game was tied 4-4 when he was pressed into action due to Georgiev's struggles. Shesterkin likely won't get an easier win all year, but he's racked up plenty of tough ones already, posting a 9-3-2 record with a 2.33 GAA and .931 save percentage so far this season.
