Bournemouth followed up their shock Carling Cup win over Blackburn by giving Doncaster their heaviest defeat since their return to league football two years ago with a 5-0 mauling at Dean Court.
It could have been a lot worse for Rovers - who enjoyed a cup shock themselves with a 2-0 win over Ipswich - had it not been for the excellent performance of keeper Andy Warrington.
The game was over as early as the 25th minute when Bournemouth rampaged into a four-goal lead.
They were ahead after three minutes when Wade Elliott got down the right and centred for Dani Rodrigues to glance home his first goal for the club.
Two minutes later Elliott again got free and his centre was headed home by James Hayter.
Doncaster briefly rallied and Neil Moss made an important save from Leo Fortune-West but it was a rare moment of relief for the travelling fans.
Elliott fired over from 15 yards and Hayter drilled a shot against the goalkeeper's legs as Bournemouth continued to look menacing.
A third goal was inevitable and it came in the 19th minute when Eddie Howe, on loan from Portsmouth, scored his first goal in open play and more than two years when he turned in a corner on the right from Brian Stock.
Doncaster were still reeling when they conceded a fourth goal in the 25th minute, the victims of a classic break away goal. Goalkeeper Moss collected a corner, threw it out to John Spicer who then swept at a pass out to the overlapping Warren Cummings and his centre was turned in by Gareth O'Connor.
Doncaster almost pulled a goal back in first half injury time when Guy Ipoua headed a free kick from substitute Steve Mulligan against the bar.
But soon after the break it was Warrington again defying Bournemouth this time twisting backwards to turn over a dipping shot from Rodrigues.
Doncaster had five players booked on a miserable afternoon with Doolan, Ipoua, Mulligan, Coppinger and Albrighton all shown yellow cards for fouls.
Bournemouth's fifth goal came on 70 minutes with Howe intercepting in midfield and feeding Spicer on the right and his ball found Hayter who was perfectly placed to beat Warrington with a low shot.
