Gavin Duffy, John Muldoon, Mike McCarthy, Brett Wilkinson all made the starting XV while versatile prop Ronan Loughney will look to impact from the bench. The call-ups are just reward for recent fine form and though Connacht had to wait until their final pool game in the Heineken Cup to earn their first victory there have been some exceptional individual performances along the way.
In the forwards, Damien Varley starts at hooker and beside him experienced Connacht loose head prop Brett Wilkinson packs down with Stephen Archer, who has recently broken into the Munster match squad and been part of his provinces Heineken Cup run.
A dominant Connacht pack pinned Harlequins deep in their own half and with a gale blowing straight down the pitch 'Quins were unable to kick for territory. The pressure showed after just 4 minutes when Niall O'Connor found his range with a 35m penalty after Harlequins were caught offside. The visitors struck back straight away with a combination of pick and drives before unleashing the backs from right to left, Sam Smith scoring in the corner after referee Nigel Owens had to consult the TMO. Nick Evans missed the conversion and 2 minutes later Niall O'Connor added his second penalty to put the home side back in front at 6-5. Superb breakdown work from Connacht earned them another penalty after just 15 minutes and Niall O'Connor extended the lead to 4 points with his kick.
The side sees just one change from the team that took on Toulouse in Stade Ernest Wallon last weekend with Ronan Loughney replacing Dylan Rogers at tighthead prop. Loughney was called into the Ireland Wolfhounds squad yesterday along with 4 other Connacht players, Brett Wilkinson, John Muldoon, Gavin Duffy and Mike McCarthy while Tiernan O?Halloran was called in as an additional player to the Senior Ireland squad.
