Luke Johnson, Dominik Kahun, Marcus Kruger, Andreas Martinsen and John Hayden each scored in Chicago’s first victory of the preseason. Johnson’s goal came on the power play, while Kruger and Martinsen each recorded the primary assist on each other’s tallies.
Alex Formenton and Matt Duchene each beat Hawks goaltender Collin Delia to give the Senators a 2-0 lead in the first period.
Delia kept the Hawks in the game with big stop after big stop. He made 17 saves on 19 shots in 32 minutes, 22 seconds of ice time before Matt Tomkins entered.
Chicago dominated possession and left Tomkins at the other end with not much work. He faced his first shot at 4:40 in the third frame.
Dylan and Tyler Sikura made history by being the first brothers to play in the same game since Sept. 20, 2011, when Jonathan and David Toews did the same.
The Hawks start the second half of their preseason schedule Tuesday against the Detroit Red Wings at the United Center in Chicago.
