LAHORE - The Pakistan Cricket Board's effort to hold a home series received another jolt with the West Indies refused to accept an invitation to play a few One-dayers in the country. After being snubbed by Australia, India and Sri Lanka for security and other reasons, the PCB has now been told by the West Indies Cricket Board (WICB) that they can't undertake a tour in August due to prior engagements. The PCB has invited the West Indies and New Zealand to play three-match ODI series in August to give its team some practice before the Champions Trophy in September. This would have also helped PCB recover from the financial setback it suffered due to the postponement of Australia's tour in March. "Yes, the West Indies board has informed us that since they are already committed to playing some games in Canada in August, they can't accept our invitation," Shafqat Nagmi, PCB's chief operating officer, said. "We have sent a fresh invitation to New Zealand asking them to come and play a full five-match One-day series instead of three ODIs. We are awaiting a reply from them," Naghmi added. He, however, said even if New Zealand turned down the offer it would be coming to play the original three-match series before the Champions Trophy. The PCB is also in talks with Cricket Australia to split its postponed tour into two halves with the Aussies first visiting Pakistan this year for the One-dayers and then next year in March for the Test series.
