Wasps v Bath preview

Aviva Premiership sides London Wasps and Bath clash in Sunday's Amlin Challenge Cup semi-final at Adams Park.

London Wasps host Bath in Sunday's Amlin Challenge Cup semi-final at Adams Park looking to keep up their bid for a second success in the competition.

The clash is a repeat of the 2003 final between the sides, which Wasps won 48-30 to claim their only success so far, while the defeat was Bath's only appearance in the final.

Both sides go into the Sunday's game on the back of Aviva Premiership wins last weekend, with Wasps beating Gloucester 38-30 and Bath overcoming bottom side Worcester 32-20.

The pair will face either Northampton and Harlequins in this year's final - with their fellow Aviva Premiership sides playing their semi-final clash on Friday.

Both Wasps and Bath are unbeaten in the competition so far - with both winning their respective pools with six straight victories, before Bath knocked out Brive 39-7 in their quarter-final, while Wasps beat Gloucester 36-24 to reach the last four.

There is only one change to the Wasps squad that recorded their bonus-point win against Gloucester last weekend.

Phil Swainston starts at tighthead in place of Jake Cooper-Woolley, who is ruled out through injury. Taione Vea comes onto the bench.

Opponents Bath have made six changes to the side which earned a bonus point victory over Worcester.

Anthony Perenise, Dominic Day, Guy Mercer, Peter Stringer, Jonathan Joseph and Semesa Rokoduguni all return to the starting line-up.

Perenise returns to the front row, while Day takes his place at lock alongside captain Stuart Hooper.

Mercer comes onto the openside flank, Stringer combines with George Ford in the half-backs and Joseph resumes his midfield partnership with Kyle Eastmond. Rokoduguni lines up on the wing.
