Dan Biggar delivered an immaculate goal-kicking display as the Ospreys launched their Heineken Cup campaign with a 28-21 victory over French heavyweights Biarritz.
Former England wing Iain Balshaw scored two tries for Biarritz, but his opposite number Tommy Bowe's second-half touchdown - and 23 points from Biggar - ensured a winning start in Pool Five for the Welsh regional side.
Biggar landed seven penalties and a conversion with his eight kicks at goal, finishing just three points short of equalling Gavin Henson's Ospreys Heineken Cup record of 26 against Harlequins seven seasons ago.
Biggar's unswerving accuracy was responsible for the Ospreys extending their unbeaten European home record to 17 games since they lost at home to Leicester in December 2005.
At times they made hard work of it, struggling for fluency in their attacking game, but with Biarritz regularly conceding penalties Biggar was in no mood to let them off the hook.
He kept the scoreboard ticking over and allowed the Ospreys an early opportunity to take charge of their group.
Having been Heineken quarter-finalists in three of the last four seasons, the Ospreys are determined to go at least one step further this time around.
And victory over Italian hosts Treviso next weekend would send them into next month's double-header against Aviva Premiership champions Saracens in confident mood.
