VIDARBHA’S decision of batting first backfired on them as they were bundled out for a mere 166 runs in 48.2 overs against Odisha on the opening day of their four-day Elite Group league match of the Under-23 CK Nayadu Trophy in MGM School of Sports, Cuttak on Sunday. As Many as 16 wickets fell on the day as five Vidarbha batsmen got decent starts but paid the price for poor shot selection.
