Lawrence Dallaglio made a try-scoring return to action as Wasps beat London Irish in the EDF Cup at Adams Park.

The start to Dallaglio's season was delayed by an operation to remove the metal plate that was inserted into his broken ankle on the 2005 Lions tour.

But the Wasps captain made an immediate impact and was driven over from a lineout after just seven minutes for the opening try.

Riki Flutey's score for the Exiles ensured the match was tied 10-10 at the interval but Wasps pulled clear in the second half with a brilliant finish from Tom Voyce.

The England coaches will have had a firm eye trained on events in High Wycombe today.

Not only did Dallaglio start, but England prop Phil Vickery made his Wasps debut and enjoyed his first 53 minutes of action since undergoing a third back operation in January.

Wasps also started with Danny Cipriani, the Wasps Academy fly-half who was called up to train with the senior England squad.

The under-19 international has long been tipped as a Test star of the future but he made a nervous start on his first full Wasps appearance this season.

Cipriani's first two penalty attempts flew wide and he missed touch too often, allowing a dangerous London Irish back three the chance to counter-attack.

But his early mistakes did not stop Wasps from claiming a seventh-minute lead. Blind-side flanker James Haskell was in excellent form and galloped clear down the left wing to set a platform in the Irish 22.

Wasps forced the penalty, went for touch and Dallaglio was driven over from the lineout.

David Docherty halted Sailosi Tagicakibau's powerful charge down the left but Wasps were soon punished.

The Samoan returned another wayward Cipriani clearance with a jinking run to beat Simon Amor's attempted tackle before slipping the scoring pass to Flutey.

The try followed Barry Everitt's first penalty and earned the Exiles a brief lead, which Cipriani pegged back just five minutes later from in front of the posts.

London Irish flanker Steffon Armitage was sin-binned for colliding with Wasps lock Richard Birkett as he chased a kick forward.

It seemed a harsh decision from the New Zealand referee Andrew Small but Wasps could not take advantage.

Hooker Jonny Barrett thought he had scored from a clever lineout move and break down the short side but he was called back for a forward pass.

Cipriani missed his third shot at goal and Everitt scuffed an attempt of his own as the game headed into half-time tied at 10-10.

Wasps retained the numerical advantage on the restart after Delon Armitage had replaced his brother in the sin-bin just before the interval for a high tackle on Amor.

This time Wasps stung the Exiles. Four minutes into the second half Voyce scooped up a loose ball and picked a superb angle to beat full-back Michael Horak and flanker Kieron Roche and score by the posts.

London Irish introduced new signing Seilala Mapusua to add ballast to the midfield but Wasps continued to look the more dangerous side.

Voyce was a constant threat but Wasps attack was almost too frenetic and they could not conjure up another clear scoring opportunity.

Veteran fly-half Alex King assumed the kicking duties after he was introduced and landed two penalties which carried Wasps to victory and denied London Irish a losing bonus point.
