Leason’s short-handed goal gave Anaheim a 1-0 lead at 10:39 of the first period. Leason scored on a wrist shot from the left face-off circle on a 2-on-1 set up by defenseman Cam Fowler’s long pass.
Ryan Donato tied it 1-1 at 11:27 on the same power play, scoring on the rebound off Taylor Raddysh’s shot after feeding him the puck from behind the net.
Leason put Anaheim back up 2-1 at 1:51 of the second period on a wrist shot between Mrazek’s pads off a pass from Urho Vaakanainen.
Kurashev tied it 2-2 at 3:25, capping a 2-on-1 rush by taking a cross-ice pass from Bedard and scoring from the right circle.
Seth Jones gave Chicago a 3-2 lead at 11:49 after taking a pass in the right circle from Foligno during a 4-on-3 power play.
Bedard scored at 19:31 to extend it to 4-2, taking a cross-ice pass from Kurashev and putting a one-timer past Gibson for his 20th goal of the season.
“Scoring goals is nice, kind of those round numbers, but it's not something I really thought about too much,” Bedard said. “But, yeah, I guess it’s good.”
MacKenzie Entwistle pushed it to 5-2 at 2:43 of the third period, scoring from in front after Andreas Athanasiou carried the puck to the net.
“Give them credit,” Ducks coach Greg Cronin said of the Blackhawks. “It’s a 4-2 game, and they came out the second or third shift of the third period and stripped us of the puck on a forecheck and made it 5-2. We’re trying to get back into the game and make it a one-goal game. They make it 5-2, and now you’re chasing the game.”
