GROS ISLET, St Lucia – West Indies’ batting came squarely under the microscope on Thursday’s eve of the the decisive second Test, with captain Kraigg Brathwaite urging his side to be disciplined, but positive, in a bid to square the two-match rubber and avoid their first series defeat of the year.The home side’s batting was palpably at fault for the heavy innings and 63-run defeat in the opening Test, which never got past lunch on the third day last Saturday.Strangely opting to bat first, West Indies were rolled over for 97 – their lowest ever total against South Africa – and fared little better in their second go around, dismissed for 162 in two sessions.
