ISLAMABAD: Pakistan chief selector Mohsin Khan is unhappy with some of the players selected for the two-Test series against West Indies and threatens to quit if they are not replaced by Wednesday. The former Pakistan opening batsman told the Associated Press Tuesday that his selections were ignored in the 15-member squad. “I have asked the Pakistan Cricket Board to let me know by Wednesday afternoon whether they are making changes or not. I will resign if they are not replaced by then,” said Khan, adding that he will hold a news conference at that time. Khan is reportedly at odds with the rest of the selection panel of Asif Baloch, Mohammad Ilyas, Azhar Khan and Farrukh Zaman. Baloch is the only one who has never played Test or One-Day International cricket. The first Test against West Indies begins at Guyana on May 12. St. Kitts will host the second Test from May 20. Windies break drought Pakistan's Mohammad Hafeez made a century but West Indies restored some of its battered pride with a rain-affected win in the fourth One-Day International in Barbados Monday. Dwayne Bravo struck a six in the final over before a downpour finished off the game, giving Darren Sammy's team victory by one run through the Duckworth-Lewis scoring method. Pakistan leads the five-match series 3-1. It is the first time West Indies has beaten a Test side, other than Bangladesh, in an ODI since June 2009. Pakistan compiled 248 for nine in 50 overs, Hafeez smashing seven fours and three sixes as he hit 121 from 138 balls before being bowled by leg-spinner Devendra Bishoo. Bishoo was again the top wicket-taking threat for West Indies, snapping up 3-37 in 10 overs. The key partnership for Pakistan was a second-wicket stand of 153 from Hafeez and Asad Shafiq (71). Rain meant West Indies chased a reduced target of 223 from 39 overs. With Marlon Samuels and Dwayne Bravo at the crease and rain closing in, instructions were given from the pavilion as Afridi bowled what turned out to be the 30th and final over. Bravo pulled a short delivery over mid-wicket for six which put the home side just ahead of the Duckworth-Lewis target and they played back two balls before the heavens opened and a total of 154 for four from 29.5 overs was enough for the win.
