Mumbai: Chief cricket selector Dilip Vengsarkar has singled out the batsmen as the major reason for India's disastrous showing in South Africa where they lost both the one-day and Test series.

"The batting really collapsed. I think that was our strong point, but they really messed it up. That's what I feel," Vengsarkar told the media on his arrival from South Africa in the wee hours here today.

India lost the one-dayers 4-0 and the Tests 2-1.

Following the reversal, a complete shake-up is expected in the team for the upcoming home one-day series against West Indies and Sri Lanka.

Vengsarkar, however, was less forthcoming when asked about the likely composition.

"As I said, I really don't know what will happen now. We (the national selectors) meet on the 10th" to pick the team for the first two ODIs against the West Indies and also the World Cup probables, the former India captain said.

On the decision to play seamer Munaf Patel ahead of off-spinner Harbhajan Singh in the third Test at Cape Town, Vengsarkar said, "In hindsight you can say many things in which I really do not believe in."
