Australia play their first tour match against Somerset in the last week of June, with the first Ashes Test beginning on 10 July at Trent Bridge.Fraser confirmed he had spoken to Adam Voges, who will play for Middlesex in the FLt20 this summer, about the possibility of filling in for Rogers.Neil Dexter will replace Rogers as Middlesex's captain for the four-day game while the Sydney-born player is on duty with the national side.That has been part of our contingency and he is someone we have talked about in that position, he said. Chris's selection hasn't come totally by surprise," Fraser said. "You watch his performances, the fact he is continually one of the top run-scorers and the fact Australia's batsmen haven't exactly been piling on big scores.We're chuffed for him," Fraser said. "Everybody at the club is delighted for Chris and that we as a club have played a small role in that.He'll play our first eight Championship matches and hopefully YB40 cricket until the 22 or 23 of June.We want all our cricketers to fulfil their ambitions. He has an impressive first-class record and has had a positive effect at Middlesex.Hopefully the player we've got in mind will join up the next day. If it all goes according to plan it could dovetail nicely.
