Connacht pulled off one of the upset wins of the Heineken Cup season after beating Biarritz 22-14 at the Sportsground on Friday.
It was only Connacht's third victory in Heineken Cup history, adding to previous successes against Harlequins and Zebre, and leaves them second behind Quins in the Pool Three standings.
A Dimitri Yachvili penalty in the second minute got the ball rolling for the visitors, though they were quickly pegged back by Fetu Vainikolo's converted try.
Vainikolo snapped up a Dave McSharry offload before crossing the line, and Dan Parks made no mistake with the extras to raise home expectations at this early stage.
At the end of the first quarter, Yachvili's second penalty of the evening narrowed the deficit to a single point, though Parks' drop-goal barely two minutes later gave Connacht breathing space.
The scores remained at 10-6 until the final minute of the first period, when a third Yachvili penalty ensured there was little between the teams at half-time.
Parks had contributed half of his side's points in the first half and he was at the centre of attention once again following the restart - hitting two penalties in the first fifteen minutes of the second half to stretch Connacht's lead.
The former Scotland pivot added a second drop goal of the match eight minutes from time to set up what would prove to be an unassailable advantage.
A penalty from Parks two minutes from full-time rubbed salt into the wounds for Biarritz, whose consolation try from Imanol Harinordoquy in the final minute did little to erase feelings of disappointment following an indifferent performance from the French outfit.
