SUMMER signing Phil Dowson will captain Warriors in Saturday's game against the Barbarians at Sixways (3pm).

Dowson is one of six players that have joined this summer to be named in Dean Ryan's starting 15.

In the backs, Worcester supporters will get a first glimpse of new half-back combination Tom Heathcote and Luke Baldwin, while Andy Short will play for Warriors for the first time since rejoining the club from Bristol.

In the forward pack, Na'ama Leleimalefaga, Carl Kirwan and Dowson are all set to make their debuts.

Recent loan signing Marco Mama and new academy lock Charlie Hewitt could also step out for Warriors for the first time if they appear from the bench.

Chris Pennell will feature at Sixways for the first time since his last-minute try against Bristol  helped Warriors back to the Aviva Premiership, while Cooper Vuna, Max Stelling and Ryan Mills complete the backline.

Dan George and Joe Rees occupy the front-row with Dan Sanderson and Darren O'Shea in the second-row, while there is a place at flanker for Matt Cox.

Meanwhile, the Barbarians have named a side including 2011 Rugby World Cup winner Ali Williams and fellow All Blacks Carl Hayman and Adam Thomson.

Australian prop Benn Robinson and South African internationals Pierre Spies and Wynand Olivier also start for the Baa-Baas, who defeated Samoa last weekend.
