Barnsley registered their second successive away win with a comfortable win over a poor Ipswich side.
After home striker Tamas Priskin's shot was tipped on to the bar by Luke Steele, Barnsley took the lead when Goran Lovre volleyed in from six yards.
Adam Hammill's 25-yard shot hit the post and bounced in off the back of keeper Marton Fulop to make it 2-0.
Garry O'Connor steered home Lovre's cross for the third before Tommy Smith headed in a consolation for the hosts.
While Barnsley will be delighted with victory, Ipswich's performance did not go down well with the home crowd.
Manager Roy Keane was urged to "sort it out" by fans, who ended the game ironically cheering every Barnsley pass.
Ipswich were not helped by being without several players and Grant Leadbitter's suspension saw on-loan Jack Colback moved into the centre of midfield.
The youngster made his mark with a cynical challenge on Lovre which saw him booked inside three minutes.
Barnsley enjoyed lengthy spells of possession but Ipswich came close to opening the scoring when Priskin fired in a shot from the edge of the area that Steele pushed on to the bar.
Priskin was unlucky but Ipswich could have few complaints when Lovre put the Tykes ahead in the 21st minute with his first goal for the club.
The influential Hammill carried the ball forward and dug out a deep cross to the far post, Jim O'Brien timed his run well to head the ball back across the face of goal to leave Lovre with the simple task of volleying into the net from six yards.
The Portman Road crowd were growing restless and were incensed moments later when O'Connor waltzed through a statuesque backline but dragged his shot wide.
However, Hammill soon found his range again with a powerful shot from 25 yards which struck the foot of the post and cannoned into Fulop's back before nestling in the back of the net.
Any hope of an Ipswich comeback was extinguished within five minutes of the restart when O'Connor made it 3-0 with his third goal for the visitors.
Lovre took advantage of some slack marking to break clear on the left wing before supplying a low ball into the goalmouth which the on-loan Birmingham man steered inside the near post.
Ipswich got a goal back late on when Smith powered in a header from a Carlos Edwards corner.
