New Delhi: India A's problems on their Caribbean tour have mounted with an injury to Robin Bist, who fractured his right thumb while fielding in the last unofficial Test against West Indies A in St. Lucia. Further, the squad has not been able to summon up a replacement in Mandeep Singh, according to reports in an Indian daily, due to rigmarole visa formalities. Bist, the highest run-scorer in the recent Ranji Trophy season, was drafted into the XI for the third and final match of the series, but after scoring 5 in the first innings was unable to bat in the second due to injury. According to reports, the national selectors wanted to send Punjab opener Mandeep Singh, who sparkled for the Kings XI Punjab in IPL 5, but the Punjab opener will not be able to link up with the squad due to a visa glitch. India A lost the series 1-2 to West Indies A, and there are still three one-dayers and two T20s to be played on the tour.Earlier, when Delhi pacer Parwinder Awana was pitch-forked into the team as replacement for RP Singh, who was ruled out of the tour due to injury, it took Awana almost a fortnight to get the visa clearance and he eventually left for the Caribbean on June 10. âItâs a lengthy process and so it would have been tough for Mandeep to reach the West Indies in time for the rest of the matches,â a top BCCI official was quoted as saying to an Indian daily on Wednesday.Mandeep cracked 432 runs in 16 matches in IPL 5. âHe is a promising cricketer and he will surely make the cut when the A team plays in New Zealand in September,â an insider told the newspaper. India A will tour New Zealand in September-October to play two four-day matches, three one-day games, and one T20 against New Zealand A.
