MONTREAL -- Andrei Kostitsyn and Mathieu Darche scored second-period goals and Robert Mayer stopped 19 shots to lead the Montreal Canadiens to a 4-2 preseason victory over the Ottawa Senators on Friday night.
P.K. Subban and Dustin Boyd also scored for Montreal (1-1).
Mike Fisher and Ryan Keller scored for Ottawa (1-2) and Pascal Leclaire made 24 saves.
Former Senators goalie Alex Auld stopped 11 shots in his first outing with the Canadiens. Mayer took over 9:38 into the second.
Kostitsyn gave Montreal a 2-1 lead 10:50 into the second when he jumped into the slot to intercept Ottawa veteran Chris Phillips' cross-ice pass before firing a low shot past Leclaire.
Darche put the Canadiens up by 3-1 with a power-play goal at 15:50, taking a feed from David Desharnais to finish off a nice passing play begun by defensemen Brendon Nash and Mathieu Carle.
Keller scored late in the second to draw the Senators to 3-2. Boyd restored Montreal's two-goal lead in the third.
The Northeast Division rivals will meet again Saturday night in Ottawa.
