Metro will remain open an extra hour Monday for fans attending Game 4 of the Stanley Cup Final at Capital One Arena.
Xfinity is footing the $100,000 bill to keep weeknight service open until 12:30 a.m., the transit agency announced.
This follows the pattern of different companies and organizations stepping up to sponsor extended Metro service to accommodate hockey fans in downtown D.C., including earlier this postseason when the Washington Capitals hosted the Pittsburgh Penguins and the Tampa Bay Lightning.
The Capitals are playing the Vegas Golden Knights for the Stanley Cup, with the series tied 1-1 after two games in Las Vegas.
