Chris Henry and Louis Ludik added second-half scores while man of the match Ruan Pienaar converted all five. Willis Halaholo and Alex Cuthbert crossed for home consolation tries. Wales captain Sam Warburton was a late withdrawal from the Blues side with a sickness bug, despite recovering from the shoulder injury which kept him out of Wales' win over South Africa. Shingler's early long-distance penalty was the only score of a cagey opening quarter, before Ulster took control with three converted tries in 13 minutes. A snipe from Pienaar set up the attacking position for All-Black Piutau to bag an overlap try after 24 minutes, with opposite number Blaine Scully in the sin-bin for killing the ball at a ruck. Four minutes later giant centre McCloskey cut through on a clever angle from 20 metres out to stroll through some weak Blues defence. Scully's return did not prevent Ulster turning the screw as prop McCall bundled over from close range following Pienaar's charge-down of Lloyd Williams' attempted clearance, Pienaar again converting. The Blues finally roused themselves for hooker Dacey to be driven over with the final move of the first half, making it 21-8 at the break.

Even with Marshall off, a clinical Ulster bagged the bonus point as Chris Henry crossed, following a break-away led by Pete Browne and Tommy Bowe. Crowd favourite, former Wales fly-half Nicky Robinson, returned to Blues colours in the final quarter and converted a jinking effort by Halaholo with ten minutes left, before putting Cuthbert over and goaling again. But replacement Ludik eased any Ulster nerves by scrambling over from a charge-down to leave the Blues pointless.
