Shaun Marsh has had wonderful start to his ODI career and the world has seen what he did in IPL season this year. He indeed will be an asset to the aging Australian side. With both openers Katich and Hayden in mid 30s, inductinga young player would be an excellent option. Hope he does well in career in Tests as well. On after thoughts - from his next series against NZL and RSA and not in current series vs IND.
He has already proved his batting capabilities in India and hence our Indian bowlers also have to keep a eye on him. We have seen him give good starts to Kings eleven and that should not be made to happen in tests.
