Halliday scored a power-play goal on two shots and blocked three shots in Monday's 4-1 win over the Devils.
Halliday has two goals on the year, and both have been game-winners. Over six appearances, he's added seven shots on net, eight blocked shots and three hits. The 24-year-old is holding firm on the Senators' fourth line, but he's also featuring on the second power-play unit, which should help support his scoring output.
