The rookie has started 11 of Chicago's 17 games this season, but the 25-year-old said he doesn't have any kind of edge on Malcolm Subban and Collin Delia, the other two goalies who have played for the Blackhawks this season.
"I'm here for the first year," Lankinen said. "Whenever I get the chance to start, I'm going to earn my net. Whenever I get the start, I'll just do my best and go from there."
Lankinen is likely to start again for the Blackhawks when they play at the Detroit Red Wings on Wednesday (7:30 p.m. ET; NBCSN).
He is 6-2-3 with a 2.49 goals-against average and a .925 save percentage, statistics that are more impressive considering he never played an NHL regular-season game until Jan. 19, when he made his debut against the Florida Panthers.
"He's such a hard-working and driven individual, it's not surprising, really," Blackhawks developmental goaltending coach Peter Aubry said. "Especially with the consistency component. He brings the same thing, day in and day out, whether he has a practice jersey on or a game jersey on. I feel really good about the fact that he's doing it day in and day out."
Lankinen has been tested but he hasn't been rattled. He allowed five goals on 30 shots in his NHL debut, a 5-4 overtime loss to the Panthers, and six goals on 43 shots in a 6-5 loss to the Columbus Blue Jackets on Thursday.
But after each loss, coach Jeremy Colliton started Lankinen the next game, and he responded each time. He made 30 saves in a 4-1 win against the Red Wings on Jan. 22 and 29 saves in a 3-2 overtime win against the Blue Jackets on Saturday.
He's allowed two goals or fewer in seven of his 11 starts, and his eight starts with a save percentage of .900 or better is tied for third in the NHL, behind Semyon Varlamov of the New York Islanders and Andrei Vasilevskiy of the Tampa Bay Lightning (nine each). Lankinen's .936 even-strength save percentage is sixth in the NHL among goalies to play at least five games.
"I love his composure, his demeanor, how he carries himself, and I wanted to give him a chance to respond to it right away instead of sitting on it a bunch of days," Colliton said Saturday. "It's a hard league, so you're going to be tested every day. He's been really good for us."
