Detroit earned the game's first power play when Marcus Johansson was sent off for holding at 6:49 of the first, and the Red Wings used that extra-man opportunity to grab an early 1-0 lead. Henrik Zetterberg made a terrific backhand saucer pass across the crease to Frans Nielsen, who had quietly crept down to the back post. Nielsen put his initial shot off the goalpost, but it bounded right back to him and he put his second try behind Caps goalie Braden Holtby for a 1-0 Red Wings advantage at 8:13 of the first.
Washington came out of that first period trailing by a goal for the first time in nine games, and the hole got a little bit bigger just a few minutes into the second. Detroit winger Anthony Mantha picked off John Carlson's indirect pass in the neutral zone, creating a short-iced two-on-one. Mantha fed Zetterberg, who waited and then fed the late guy into the zone, Tomas Tatar. Tatar's shot from the slot beat Holtby to move the Detroit advantage to 2-0 at 3:33 of the second stanza.
The Capitals' hands seemed slow for most of the game up to that point; passes didn't have their usual zip and triggers weren't pulled with their usual swiftness. But the Caps kept at it and finally - in the penultimate minute of the second period - they were able to cut into the Red Wings' lead with a critical goal.
Lars Eller forced a turnover in neutral ice, and then carried into the zone with linemates Brett Connolly and Zach Sanford. He threaded a feed to Sanford, whose shot beat Red Wings' goaltender Petr Mrazek, cutting the Detroit lead to 2-1 just 84 seconds ahead of the second intermission.
