Latics bowed out of the Emirates FA Cup as Bournemouth struck three times in the second-half to progress at the Vitality Stadium.
A penalty from Dylan Bahamboula meant Harry Kewell’s side went in level at the break after an excellent display in the first period, which also saw them hit the woodwork through Jordan Barnett.
But having fought back once after going behind, Latics were unable to do so again, Rodrigo Riquelme restoring the home side’s lead within three minutes of the re-start and Bournemouth duly took control.
Having had this Third Round tie switched to the South Coast due to the recent wintry conditions at Boundary Park, Latics should take heart from their first-half showing against the Sky Bet Championship high-flyers but it was ultimately a convincing win for Jason Tindall’s side. #oafc
The first-half was eventful, Bahamboula sending a shot into the side netting within the first minute after neat footwork to cut in from the right wing.
Carl Piergianni’s glancing header from a Barnett corner was touched away by goalkeeper Will Dennis, and although the home side had a sustained period of possession midway through the first half, it was Latics who had the better moments.
Their football was bright, Davis Keillor-Dunn turning well on the edge of the area before firing over and Bahamboula shooting at Dennis, while at the other end David Brooks and Riquelme had chances.
Latics came within inches of taking the lead just after the half-hour when Barnett sent a fantastic curling effort towards goal, only for the ball to cannon off the post.
It was against the run of play that Bournemouth took the lead, Brooks scoring via a deflected shot from 20 yards.
Yet Latics were rewarded for their good pay when Keillor-Dunn was brought down by Dennis, allowing Bahamboula to convert emphatically from the spot.
The second half, however, was a very different story, Riquelme converting from close range on 48 minutes and the hosts proceeded to take command.
Goalkeeper Ian Lawlor saved from Zemura and Josh King, who added the third with 16 minutes to go, finding the target with a close-range header.
King completed the scoring late on with a neat turn and finish, meaning the home side progressed with a comfortable win.
