A sparkling display from Ishmael Miller helped West Brom dominate Norwich and earn a comfortable victory.
On-loan striker Miller put Albion in front 15 minutes into the game when he headed in Bostjan Cesar's cross.
Shortly before half-time, Miller almost scored again when he struck a powerful drive that grazed the crossbar.
After the break, Kevin Phillips met Miller's cross to double the advantage with a downward header that went just inside the far post.
West Brom boss Tony Mowbray:
"I felt we controlled the match from start to finish and I'm disappointed we didn't score more.
"I'm not trying to be critical, but I want the team to know how to win and sometimes we were over elaborate.
"I am happy enough with the day, but there is plenty of improvement in us. Clean sheets are the key to promotion so we're pleased with that."
Norwich caretaker-manager Jim Duffy:
"It was a very difficult afternoon. They are a good side, we can't disguise that. Their movement is excellent and they are dynamic.
"We barely performed in the first half, last-ditch tackling and goalkeeping
was the only thing that saved us.
"In the second half I thought we were better. We've got to look just to be better, but it's a slow process."
