Daniel Alfredsson scored an empty-net goal and added an assist in his return to Ottawa, and the Detroit Red Wings beat the host Senators 4-2 on Sunday night.
Alfredsson, the former longtime captain of the Senators, wasn't primarily responsible for Ottawa's second straight loss and fourth consecutive at home, but he helped contribute to the continuation of his ex-team's woes.
Like so many times in their previous 27 games in the post-Alfredsson era, something was missing for the Senators (10-13-4). Defensive breakdowns led to goals, and there wasn't enough offense to compensate.
Drew Miller scored twice, Johan Franzen added a goal, and Jonas Gustavsson made 29 saves for Detroit.
Clarke MacArthur and Mika Zibanejad had goals for Ottawa.
The Senators were 0-for-4 on the power play, and the Red Wings seemed to capitalize on every mistake.
