Bournemouth moved to the top of the Championship as two goals in each half saw them ruthlessly defeat Barnsley.
In an open game with several chances at both ends, the Cherries led when Philip Billing found the bottom corner with a low strike from 20 yards.
The hosts should have levelled, but defender Mads Andersen could not sort out his feet in time to divert Michal Helik's effort in from two yards, and were punished as Dominic Solanke doubled Bournemouth's lead with a run and near-post finish on the stroke of half-time.
Diego Rico made it 3-0 with a fine free-kick which caught out Barnsley keeper Jack Walton - who expected a cross - with Sam Surridge capitalising on an error to complete the scoring with a shot that Walton should have kept out.
