Ullmark made 27 saves in a 3-0 win over Toronto on Tuesday.
The shutout was Ullmark's ninth in the NHL and his first since being acquired from the Bruins in the offseason. He has won two straight against Toronto and Boston, improving to 4-4-0 with a 2.51 GAA and .904 save percentage. Overall, the Senators played a strong game in front of Ullmark, and more such defensive performances would go a long way in helping the Swedish netminder replicate the success he had in Boston.
