Conor Sammon scored against his former club to help Rotherham to a surprise win over promotion hopefuls Ipswich.
The striker, who spent the first half of the season on loan at Portman Road, lashed home from close range after the visitors failed to clear a corner.
Matt Derbyshire’s earlier header put the Millers ahead as he stooped at the far post following a defensive lapse.
Rotherham goalkeeper Adam Collin made several saves, including a fingertip stop from Luke Chambers’ header.
The three points for Steve Evans’s men was just their second victory at the New York Stadium since mid-October, while Ipswich have now won once in their last six league games and drop to fifth in the table.
Daryl Murphy, the Championship’s leading scorer with 18 goals, spurned a glorious opportunity to put the visitors ahead after just 16 seconds when he burst into the box after outmuscling Millers captain Craig Morgan, but his weak effort was saved easily by the legs of Collin.
After such a bright opening, the game quietened down before the hosts opened the scoring through former Olympiacos forward Derbyshire.
Ben Pringle’s deep free-kick evaded every Ipswich player, Morgan flicked the ball on and it found its way to Derbyshire, who bravely dived in to nod home.
The visitors began the second half brightly and almost equalised when Cole Skuse’s pin-point free-kick found the head of Chambers, but his powerful header was superbly tipped over by Collin.
Shortly after Murphy’s header was cleared off the line by Zeki Fryers, the hosts went down the other end and doubled their advantage throughDerby loanee Sammon.
Pringle’s corner was not cleared by the Tractor Boys’ defence, the ball broke to Sammon and he lashed it past Polish keeper Bartosz Bialkowski.
The second goal seemed to deflate Mick McCarthy’s side as they pushed forward but failed to create any clear-cut opportunities before Millers substitute Jordan Bowery almost made it 3-0 in stoppage time, when he raced through on goal but his attempt was kept out by Bialkowski.
