Tries from Danny Care, Rob Buchanan, Jordan Turner-Hall and Seb Stegmann, complimented by 16 points from the boot of Ben Botica secured Harlequins a resounding 40-13 victory.

Botica was forced into action when Nick Evans was taken off after just 16 minutes. The 24 year-old, making his second senior appearance for the club, looked more than comfortable as he took a strangle hold on the back line and was a wizard from the boot.

The visitors, who were without household names Dimitri Yachvili, Imanol Harinordoquy and Jerome Thion, were dealt a further blow when fly-half Mathew Berquist was withdrawn due to a hip injury.

Harlequins opened the scoring after six minutes with a try from Care. It was a move which came straight from the training ground. Lineout ball was collected at the back by Chris Robshaw, the flanker popped the ball down to Care who cut through the lineout on the 22 to score under the posts. Evans converted giving the home side a 7-0 lead.

Biarritz opened their scoring on 13 minutes with a penalty from Julien Peyrelongue. This was then followed by a yellow card to Biarritz's Dane Haylett-Petty. The centre took Tom Williams in the air from a high ball and was sin-binned for his efforts.

The sin-binning was bitter sweet as Evans was taken off, but the worry was short lived, Botica nailed a penalty to lead 10-3.

Biarritz drew level with a try from hooker Arnaud Heguy. A chip kick from winger Takudzwa Ngwenya forced Ugo Monye into touch. From the lineout, the Biarritz forwards drove up to, and over the line.

This try marked the beginning of a wealth of domination from the French pack as they took control of the game.

The Harlequins pack had their backs up against the wall in the later stages of the first half, but an exchange from both kickers had the scores level at half time.

In the second half, it was the Harlequins pack that turned things around and took a strnalge hold on the game.

Ugo Monye stole the kick-off which preceded a monstrous rolling maul. From a five metre scrum, the forwards worked many phases before Buchanan scored.

Botica converted and played an inspirational role in working Quins back upfield before the fly-half added another penalty.

Biarritz wasted a promising opportunity with a stunning counter attack. Haylett-Petty broke the initial line of defence in his own 22, he offloaded to the speedster Ngwenya who was halted by Mike Brown in the Harlequins 10 metre line. With numbers out wide, Peyrelongue's cross field kick went straight into touch, killing the attack dead.

Harlequins forwards continued to dominate and Botica slotted a 47 metre penalty for fun just after the hour mark.

Man of the match, Nick Easter was inspirational in the lead up to Harlequins' third try. Breaking from the back of a scrum, the number 8 offloaded to Care. Care made 40 metres and a wide pass to Seb Stegmann brought Harlequins within five metres. The ball was shipped right and Turner-Hall bundled over. Botica added the extras from the touchline.

From here Harlequins went hunting for the bonus point score. The home side were gifted a 5m scrum and looked to have blown their chances when Biarritz were given possession from a lot lineout.

After the disappointment, Harlequins worked just short of the line with a commanding rolling maul. Maurie Fa'asavalu came close to scoring but possession was recycled. Care shipped to Brown who's quick pass found Stegmann on the wing to score the bonus point try.

Botica's touchline conversion rounded off a compelling victory for the quartered men.
