Baba Aparajith hit a half-century as South Zone posted a massive first innings total of 630 for eight before declaring on the second day of their Duleep Trophy semi-final against North Zone here on Friday. In reply, North reached 24 for no loss at stumps with the talented Yash Dhull on 8 (18 balls, 1 four) and Manan Vohra batting on 11 (12 balls, 1 fours), still 606 runs adrift of South's huge first innings score. In Coimbatore, diminutive opener Prithvi Shaw was in roaring form, hammering an unbeaten 96-ball 104 (11 fours, 3 sixes) as West Zone ended at 130 for three in the second innings to extend their lead against Central Zone to 259 runs.
