Afridi may quit ODIs after 2015 World Cup Pakistan all-rounder Shahid Afridi says he might retire from One-Day Internationals after the World Cup next year and just concentrate on Twenty20s. Afridi quit Test cricket four years ago after playing just 27 Test matches, but the hard-hitting all-rounder is a regular member of the limited-over teams. He has played in three World Cups, and captained the team to the 2011 semifinals, after which differences with Pakistan Cricket Board officials made him quit the captaincy. Pakistan's most capped T20 player, Afridi was only two games shy of Inzamamul Haq's national ODIs record of 375. “The 2015 World Cup (in Australia and New Zealand) is important for two, three senior members of the team. I may retire after it and continue playing Twenty20 cricket,” Afridi said Friday in Lahore. “I've always said that my cricket is attached with my fitness and performance, and I will take the final decision after seeing my performance in 2015.” Afridi was in favor of performance-based central contracts, and said if someone performed throughout the year he should get the A-plus category, and if a senior player's contract was reduced due to performance, he should accept it. He said he still wished to be captain again. “It's (captaincy) not a bed of roses, it's an honor for a player,” he said. — Agencies
