"The whole day was a whirlwind, but the finish to the day was unbelievable," Berlin said. "Something I'll never forget for the rest of my life."
The 25-year-old, who is in his third season with the University of Alberta, signed an amateur tryout contract on an emergency basis earlier in the day after Stuart Skinner came down with an illness.
Berlin has been an emergency backup for the Oilers for each of the past two seasons and has also occasionally practiced with the team.
"I did the EBUG last year, and then Shawn [May, Oilers communication] texted me and I thought I was going to be sitting in the stands like last year during the playoffs, and he texted me again about 4:30 p.m. saying that there was a change of plans and I was backing up tonight.
"I was sitting there doing homework and my heart rate spiked, and it was a whirlwind of a day getting ready to get down here, but it was unbelievable. Everyone was so welcoming down here, the players, staff, everybody. It was unbelievable. I was studying for a psychology midterm on Monday."
Berlin entered the game to an ovation with 2:26 remaining in the third period and made a blocker save on the only shot he faced, coming from Caleb Jones from the left point with 48 seconds left, drawing a loud roar from the crowd.
"I thought they were joking, but [Oilers coach Jay Woodcroft] said at the three-minute mark to be ready to go and that at the first whistle after the three-minute mark I was going in," Berlin said. "So I went into the back, did a couple of stretches, took a couple of breaths and I was in.
"My heart was pounding for the four minutes once he told me, and then once I got in there and got a drink of water I was all right."
