Middlesbrough's steady descent back to the Championship continued on the south coast as Bournemouth sauntered to a comfortable victory.
Boro, down to 10 men for 70 minutes following the early sending-off of Gaston Ramirez, barely offered their travelling fans a flicker of hope as they crashed to another defeat - their seventh in nine games.
For the Cherries, it was a first win in five. Josh King set the tone within two minutes and Benik Afobe added a second just after the quarter-hour mark. And from then on it it was a matter of cruise control.
Marc Pugh made it three in the 65th minute and, moments later, Charlie Daniels added a fourth.
