Dominic Solanke's 30th goal of a prolific season and a double from Philip Billing kept Bournemouth on track for promotion to the Premier League and put an end to Blackburn's play-off hopes.
Solanke slotted low into the corner to put the away side on their way to a win which sets up a tantalising meeting with in-form Nottingham Forest, who, following their 5-1 victory over Swansea, would go above Bournemouth with victory on Tuesday evening with just one game left to play.
The Cherries were equally impressive in their win and will go into the fixture full of confidence thanks to a clinical attacking display at Ewood Park.
