Shaun Marsh ready to step in for Rogers

Australia opener Shaun Marsh says he is ready, mentally and physically, to step in should Chris Rogers not be fit for the third Ashes Test at Edgbaston next week.

Rogers has been felled by an inner ear problem that affects his balance, after being struck behind the ear by a James Anderson bouncer at Lord's. Marsh, who has been on the sidelines despite excellent form, is ready if required.

The elder Marsh scored a century in the tour match against Derbyshire on Friday, retiring himself out on 101, and with this being Rogers' final Test series before retirement, Marsh is eager to show he's the best replacement option.

Marsh said on the CA website: "My mindset over the last couple of weeks is making sure I'm ready to go if there's an opportunity.

"With every opportunity I get to play for Australia, whether it's a Test match or tour match, I'm just making sure I'm ready to go and doing everything I can to score runs.

"You don't want to look too far ahead. You keep your mind in the present."

Of his century, which came off 177 balls, much slower than David Warner's 101 retired, Marsh added: "It was nice to get in a game situation.

"It was nice to get some runs …as my innings went on I got better. I feel really comfortable with my game at the moment."
