Another audition for a couple of up-and-coming forwards.

A look from the other side of the blue line for their prized defence prospect. 

And one last chance to make a statement for both backup goalie hopefuls.

Those will be among the biggest storylines Wednesday as the Calgary Flames host the Vancouver Canucks in their second-to-last pre-season game.

Teams often will dress their Opening Night lineup for the final tuneup, so this a biggie for anybody on the roster bubble.

Opportunity knocks for rookie winger Matvei Gridin, who has impressed with his blazing speed and sniped on both a breakaway and on a highlight-reel shootout attempt Monday in Seattle. The 19-year-old will skate Wednesday alongside trusted veterans Mikael Backlund and Blake Coleman.

Opportunity knocks for Rory Kerins, who certainly has opened eyes with four points in five exhibition appearances this fall. Since the 23-year-old requires waivers to be assigned to the minors, there’s growing concern that the Flames could lose him if they try to include him among their final cuts.

Opportunity knocks for Zayne Parekh, a rising righty who will play the left side in a pairing with Brayden Pachal. What will be scrutinized most closely is how the 19-year-old puck whiz handles his defensive duties against some of the Canucks’ established guns.

And opportunity knocks for Ivan Prosvetov and Devin Cooley, who will split time in the home crease. One will earn the job as Dustin Wolf’s backup while the other will be headed to the AHL. Prosvetov has better numbers so far, but could Cooley sway the decision with a better effort in his 30 minutes of action against Vancouver?

Here’s how the Flames will line up for Wednesday’s important auditions…
