Nicklas Backstrom scored, Braden Holtby had 26 saves, and the Washington Captials beat the Philadelphia Flyers 1-0 on Sunday in Game 6 to win the series 4-2 and advance to the Eastern Conference semifinals.

The Capitals will play the Pittsburgh Penguins, setting up a marquee matchup of Alex Ovechkin vs. Sidney Crosby.

Ovechkin had an assist on Backstrom's second-period goal that was easily enough against the punchless Flyers.

Riding the momentum of Michal Neuvirth in net, the Flyers won two straight to force an unlikely trip home. Neuvirth was sensational again, but the Flyers were ultimately doomed by a power play that could not cash in against Holtby. The Flyers wasted nearly 2 minutes of a 5-on-3 power play in the second period that made a critical difference.
