TORONTO - Lars Eller, Kevin Shattenkirk, Nate Schmidt and Tom Wilson scored as the Washington Capitals cruised to a 4-1 victory Tuesday over the Maple Leafs, ending Toronto's four-game win streak.
Mitch Marner, with his 19th of the season, added a late power-play goal to deny Philipp Grubauer his fourth career shutout.
The Capitals (53-18-8) could have clinched the Eastern Conference title and Presidents' Trophy on the night. But in addition to beating Toronto, they needed a Columbus win over Pittsburgh and the Penguins -- with a 4-1 victory -- weren't co-operating.
The Bruins beat Tampa Bay 4-0 to clinch a playoff spot. Toronto (39-25-15) would have joined them with a win Tuesday.
Washington, which tops the league's overall standings, has won eight of its last nine.
Toronto, which defeated the Sabres 4-2 in Buffalo on Monday, came into the game having won seven of its last eight.
