Sabres 4, Capitals 0
Washington wing Alexander Ovechkin, the top pick in the 2004 entry draft, was a non-factor in his home debut. Ovechkin took a holding penalty 26 seconds into the exhibition game and was denied on his only scoring chance of the night, a power-play shot on the doorstep with 5:56 left in the third period.
The Capitals remained winless in three preseason games and were shut out for the second time. Washington killed off nine of 10 Buffalo power plays, but was 0-for-6 on the man advantage
Vanek tallied twice in a 4:04 span late in the second period to extend the lead to 3-0.
At 15:04, he pushed in a centering pass from J.P. Dumont from the top of the crease, giving the Sabres a power-play goal after eight opportunities. Vanek notched his team-high fourth preseason goal at 19:09, again scoring from in front of the net on a play that withstood a video review.
Afinogenov scored off a pass from Derek Roy 5:29 into the third period.
