McGrath rested for 2nd ODI
Clark, who was called into the Ashes squad in England as cover for the injured McGrath, is set to make his international ODI debut.
Australia pace bowler Glenn McGrath has been rested for the second one-day international against the World XI and replaced by Stuart Clark, Cricket Australia said on Thursday.
The 35-year-old McGrath spearheaded a four-pronged Australian seam attack that strangled the free-scoring World XI and bowled them out for 162 when chasing 256 for victory in the first match at Melbourne's Docklands Stadium on Wednesday.
McGrath, who complained of tightness in his legs after the match, bowled a miserly opening seven-over spell for only 13 runs and took the wickets of Virender Sehwag and Jacques Kallis to set up Australia's crushing win.
Clark, who was called into the Ashes squad in England as cover for the injured McGrath, is set to make his international debut.
Leg spinner Cameron White, who was the supersub for the first match and made his debut when he replaced Damien Martyn during the World XI's innings, was also named in the side.
Australia: Ricky Ponting (captain), Nathan Bracken, Stuart Clark, Michael Clarke, Adam Gilchrist, Michael Hussey, Simon Katich, Brett Lee, Damien Martyn, Andrew Symonds, Shane Watson, Cameron White.
