IMO, In ODIs Lara MUST Come in at No.3, both statistics and observations of how he plays have proven that he bats better at No.3. Sarwan looks good in any position, I remember Boycott being hard pressed on him opening because he is just so impressive but I feel he should bat at 4 or 5 in ODIs and at No.3 in tests, He should bat at no.4 because he can hold up one end if needed and keep rotating the strike if Lara, gets early or if he has Lara partnering him. As for tests as Liam said , I think Wavell should be retained.
BTW, Liam, excellent observation on Wavell, that is! Also, Do you think Ryan Hinds will make a comeback, if so, how soon?
