Korpisalo made a big save with about five minutes left in the period on a 2-on-1. Devante Smith-Pelly fed Nic Dowd, but the goalie moved left to right and made the stop. Korpisalo also made a pair of nice stops on John Carlson on a late first-period power play, including a pad save on a blast from the left circle.
Columbus controlled the first half of the second period, and a scary moment came 8:43 into the period when Atkinson's stick inadvertently got caught in the mask of Holtby. The Capitals goalie left the game and was replaced by Pheonix Copley.
Just like the first, the Caps gained traction as the frame went on, but Korpisalo was strong again as the period wound down, making stops look easy on open shots from Lars Eller, Jakub Vrana and Devante Smith-Pelly.
Washington's top line turned the screws early in the third, but Korpisalo again stood tall, denying Evgeny Kuznetsov 1-on-1 and getting some help as Zach Werenski knocked a rebound away from Alex Ovechkin.
Columbus was able to put together some solid counterattacks, including a breakaway created by the speed of Lukas Sedlak, but Copley turned aside his try with the left pad.
Finally, the dam broke with 1:06 left as Washington tied the game at 1. After an icing call, the Capitals won the draw and Kuznetsov drilled in a blast from the top of the right circle off a pass from John Carlson.
In overtime, the Blue Jackets earned a power play when Boone Jenner crashed the net, and Panarin won the game at 3:30 with a one-time slap shot past Copley from the left circle on a pass from Seth Jones.
"I told him it's about time he starts scoring on that one-timer because he only practices it 100 times every day in practice," Atkinson said. "It's good to see it paying off."
