Brett Pitman scored a hat-trick as the Cherries moved up to fifth place with a win over Crewe Alexandra.
Pitman converted two penalties either side of a tap-in midway through the second half to seal back-to-back wins for the hosts.
Mathias Pogba’s strike from 15 minutes looked to have set-up a nervous end to the game with the scores at 2-1, but Pitman's third goal eased the tension inside the Goldsands Stadium.
The striker was then afforded a standing ovation by over 8,000 home supporters when he was substituted in the final ten minutes.
With Sheffield United playing Reading in the FA Cup, the Cherries overtook the Blades in the League One table, opening a five point gap between them and seventh placed Coventry.
Manager Eddie Howe made two changes, bringing in Steve Cook and Pitman to replace Richard Hughes and Charlie Daniels.
In Daniels’ absence, on loan defender Seaborne moved to left back with the Cherries opting for a 4-4-2 formation.
Crewe arrived on the south coast having not played a league game in two weeks, and they were behind after just eight minutes.
Pitman sent goalkeeper Steve Philips the wrong way and saw his penalty go in off the inside of the post after Marc Pugh had been brought down Adam Dugdale.
Pugh looked like he was in top form, twisting and turning away from his marker with ease inside the opening quarter of an hour, and was unlucky not to be awarded a second spot kick just minutes after Pitman had found the back of the net.
The winger cut in from the left and beat two players before being upended by a Crewe defender, but referee Iain Williamson wasn’t interested in his protests.
Max Clayton had a close-range header saved by Shwan Jalal as the visitors looked for a quick response, but the Cherries were soon on the attack again with Josh McQuoid guiding a header narrowly wide.
The Cherries played some great football in the first half and went close to adding a second 15 minutes from half-time.
Simon Francis charged down the right and pulled the ball back to Mcquoid, who picked out Pitman six yards out. The striker got ahead of his marker and got a touch on the cross, but couldn’t steer his header the right side of the post.
Howe’s men went into the break a goal in front, but it should have been more after Lewis Grabban rounded Phillips in injury time.
The in-form forward, who scored the winner in the midweek fixture at Hartlepool, did the hard work after getting on the end of Eunan O’Kane’s through ball, only to see his shot hit the side netting.
It seemed like there was only one man that was going to add a second for the Cherries in the second half and that was Pitman.
The striker, who signed a permanent deal with club earlier this month, had a header well saved by Phillips and curled a shot wide in a slow start after the break.
But he was on hand to tap into an empty net when McQuoid squared the rebound from Arter’s low shot.
It wasn’t all one way traffic though and Pogba gave the travelling supporters hope when he squeezed a low shot beyond Jalal.
But their hope was to be lived short lived with Pitman scoring his second penalty and his third goal of the afternoon.
He won and converted the spot kick in front of the Steve Fletcher Stand eight minutes from time to cap his man of the match performance.
Pitman then received a standing ovation as he left the field to be replaced by Richard Hughes.
There were chances late on for substitute Wes Fogden and O'Kane, but it was to be Pitman's day.
