Daley's tally early in the final stanza gave the Stars a 5-3 edge. On the play, Daley gathered in a off-target Ottawa pass in the neutral zone, came in down the right side and beat Senators goalie Pascal Leclaire with a wrist shot.
The Senators lost despite a hat trick and an assist from Jason Spezza, while Mike Fisher scored a goal and added an assist while Daniel Alfredsson chipped in with two helpers.
Leclaire was pulled after Daley's score, allowing five makers on 19 shots. Brian Elliott finished the game with six saves.
