AFC Bournemouth moved up to third place in the Premier League with their first ever away win at Southampton.
Nathan Ake's towering header sent them on their way to a 3-1 win after only 10 minutes of a first half Eddie Howe's side dominated.
On 35 minutes Harry Wilson finished off a sweeping move involving Josh King and Philip Billing to double AFC Bournemouth's lead.
Southampton rallied, with James Ward-Prowse reducing the arrears from the penalty spot eight minutes after the break following a foul on Che Adams by Steve Cook.
Ward-Prowse then went close again, while Sofiane Boufal brought a fine save from Aaron Ramsdale.
But a defensive mix-up deep in stoppage time allowed Callum Wilson to seal the points.
The win takes AFC Bournemouth up to third on 10 points, while Southampton are three points and eight places back.
