West Brom's superlative home form continued as a convincing win over struggling Blackburn saw them consolidate their hold on fifth place.
The Baggies were sure of the three points after a one-sided first half as Tom Fellows' first league goal, one from Brandon Thomas-Asante and a Dominic Hyam own goal put them in full control.
Blackburn, who have now won just one of their last nine in the league, improved after a dismal first half, with Jake Garrett pulling a goal back.
That was quickly cancelled out as Thomas-Asante took his tally to double figures for the season to make it three home wins on the trot.
