India pacer Umran Malik has said he will break Shoaib Akhtar's record of bowling the fastest delivery in cricket history. "If I do well, and if I'm lucky, I'll break that (record). But right now...I'm only thinking about performing well for the country," said Umran in an interview. Akhtar bowled the fastest ball during the 2003 World Cup, clocking 161.3kmph.
