The victory took Langerak's league record with Dortmund to eight wins and a draw but he was playing down his importance to the team as he continues to play second fiddle to Roman Weidenfeller who missed through injury.
"They're just numbers. Thankfully I have a good team in front of me! They make my job in goal really easy," Langerak told Bundesliga.com.
Regardless of his impressive record, Langerak said it was a thrill to again be out on the pitch with the first team after spending most of his time waiting for an opportunity.
"It's always nice to be out on the pitch from time to time. It was very important for the team that we got the three points today," he said.
"If you're getting a lot of match practice, it's obviously easier on the pitch. But I'm aware of my situation and know I have to be ready to play with at the drop of a hat.
"I was told on Friday that I'd be playing against Wolfsburg on Saturday, so I had one day to prepare."
