LONDON, July 6 (Reuters) - England have included pace bowler Graham Onions in a 13-man squad for the first Ashes test against Australia starting at Trent Bridge in Nottingham on Wednesday.
Onions joins Tim Bresnan and Steven Finn in a battle to decide the final place in the XI to start England's Ashes defence.
The trio played in England's warmup match against Essex for which James Anderson and Stuart Broad were rested.
Joe Root will open the batting with captain Alastair Cook in place of Nick Compton who opened in the home and away series against New Zealand.
"This is an incredibly exciting period of cricket coming up against Australia and we know we will need to play to our full potential throughout the entire Ashes Series if we are to retain the Ashes," national selector Geoff Miller said in a statement on Saturday.
"We are satisfied with our preparations so far ahead of the first test with both Graeme Swann and Stuart Broad recovering well from the injuries they picked up earlier this week."
