Blackhawks edge Blue Jackets as Brandon Hagel rips OT winner; Adam Boqvist injured

Almost every aspect of Blackhawks wing Brandon Hagel’s play this season has blown away expectations. He easily could be one of the NHL’s rookie scoring leaders, if not for his struggles to finish.

On Monday, however, he ripped the best shot of his tenure to date at the biggest moment.

Hagel’s overtime winner, which flew past goalie Joonas Korpisalo’s glove as he slid from left to right, gave the Hawks a 4-3 road victory and a sweep of the two-game series against the Blue Jackets.

‘‘[To] finally get a shooting goal . . . it’s nice to get it out of the way,’’ Hagel said. ‘‘I know I can score in this league. So [I want to] just build off stuff like that.’’

The victory capped a chaotic day in which the Hawks executed four trades, creating an emotional environment for the coaching staff and players.

‘‘You’re talking about lives and friendships,’’ coach Jeremy Colliton said. ‘‘Those are the guys you go to war with, and then all of a sudden they’re not there. It’s a tough day. And it’s tough to play a game on that day. Our guys did a really good job of understanding that, while it’s hard, [we needed to] find a way to . . . win important points.’’

It was a chaotic game, too.

Defenseman Adam Boqvist left in the first period after taking a puck to the face and didn’t return because of concussion symptoms, a massive blow for him and the Hawks moving forward.

Defenseman Nikita Zadorov was a healthy scratch in favor of Riley Stillman, who made his Hawks debut. And defenseman Calvin de Haan played despite leaving the game Saturday with a hip pointer, tweaked his injury again in the middle of the game and struggled with his mobility the rest of the night.

‘‘He gutted it out,’’ Colliton said. ‘‘He was in a tough spot, and we needed those minutes.’’

On the forward end, Brett Connolly also made his Hawks debut and scored a goal in the third period that briefly gave his new team the lead.

The Hawks rallied from 1-0 and 2-1 deficits on goals by Duncan Keith and Philipp Kurashev, then saw their 3-2 lead wiped out by a goal by the Blue Jackets’ Patrik Laine before finally prevailing in overtime.
