"To get your first shutout, that's something you always dream about," Bishop said. "I was able to see a lot of pucks and there were some key blocked shots. The guys did a great job in front of me.
"We needed the win, too."
Bishop, called up from Peoria of the AHL on Feb. 17, was starting for the injured Jaroslav Halak, who missed his fifth straight game with a bruised hand.
"He made a great statement tonight," Blues head coach Davis Payne said. "He had to make some tough saves early. He was very solid. We were able to rely on him for a little bit until we were able to build the lead a little further.
"He's a young guy that we expect a lot from now and in the future. It was another great step for him tonight."
Payne has also been impressed with Stewart, acquired in a trade with Colorado last Saturday. The forward notched his third two-goal game in the five games with the Blues.
"This is why we got him," he said. "He can score in a number of different ways and he showed a couple tonight."
The Oilers have lost two of their last three and remain in last place in the NHL.
"There needed to be more passion and emotion and contact," Oilers coach Tom Renney said. "We needed to drag ourselves into the game and we had a hard time doing that. ... It was a puzzling game. They scored on their opportunities and we kind of let them walk in and do that. And we couldn't capitalize on ours."
Stewart got the Blues on the board just 2:07 in as he skated in unopposed to lift a big rebound past Oilers goalie Devan Dubnyk.
Edmonton's Ales Hemsky clipped Barrret Jackman in the face with a high stick for a double minor late in the first and the Blues took advantage. Just as the first penalty expired, Berglund redirected Alexander Steen's shot into the goal.
Stewart's second made it 3-0 with a power-play goal at 4:19 of the second period as his shot trickled through Dubnyk's pads.
St. Louis had a good chance to make it a four-goal game with five minutes left in the second. Polak was sent in on a clean breakaway but couldn't slip the puck past Dubnyk.
Bishop continued to keep Edmonton off the board, making a big glove save on a short-handed 2-on-1 shot by Ryan Jones early in the third.
The Oilers broke down near the end of the game allowing a goal by Polak with 4:01 left and another by D'Agostini with 2:07 to go.
"It was a good team effort all the way around," Stewart said. "Bishop deserved the shutout and we had scoring from all four lines. It was a great team win."
