Sreesanth made his first run in ODIs during India's third match in the West Indies recently, which was his 16th match. Has anyone waited longer for their first run? asked Farhan Arain from Pakistan

Sreesanth's long wait for his first one-day run was indeed a record. The former West Indian fast bowler Patrick Patterson didn't trouble the scorers until his 14th one-day international, while one of Sreesanth's Indian predecessors, Venkatesh Prasad, didn't get onto the scoresheet until his 13th match.

Ramnaresh Sarwan scored a hundred in his 100th ODI - how many people have done this? asked almost everyone

Sarwan achieved the feat against India at Basseterre, in the first ODI played in St Kitts, the 158th ground to stage one. He is the seventh player to mark his 100th one-day appearance with a century, and the third West Indian. Gordon Greenidge was the first, with 102 not out against Pakistan at Sharjah in 1988-89 (the following season Greenidge completed a unique double by scoring a century in his 100th Test as well). The others are Chris Cairns, with 115 for New Zealand against India at Christchurch in 1998-99; Mohammad Yousuf (then known as Yousuf Youhana), 129 for Pakistan v Sri Lanka at Sharjah in 2001-02; Kumar Sangakkara, 101 for Sri Lanka v Australia in Colombo in 2003-04; Chris Gayle, 132 not out for West Indies v England at Lord's in 2004; and Marcus Trescothick, with 100 not out for England against Bangladesh at The Oval in 2005.

Who has scored the most runs in all World Cup matches so far? asked Dhaval Brahmbhatt from the United States

Five men have so far scored more than 1000 runs solely in World Cup matches. Mark Waugh made 1004 runs, Viv Richards 1013, Aravinda de Silva 1064, and Javed Miandad - the only man to play in six different tournaments - 1083. But way clear at the top of the list is Sachin Tendulkar, who has so far scored 1732 runs in the World Cup, at the healthy average of 59.72, with four centuries. Ricky Ponting, who currently has 998 runs, and Brian Lara (956) are likely to sail past four figures during next year's World Cup.

I remember a young player who had a sensational ODI debut for Sri Lanka, taking five wickets and scoring a few runs - but he never quite made it. Do you know who it was? asked Chad Candappa from Australia

I think you must be talking about Uvais Karnain, who took 5 for 26 and scored 28 on his debut for Sri Lanka, against New Zealand at Moratuwa in 1983-84. Karnain played 19 ODIs in all, but never improved on that bowling analysis - and he never did win a Test cap. The other Sri Lankan to take a five-for on one-day debut is Charitha Buddhika, with 5 for 67 against Zimbabwe at Sharjah in 2000-01 - but he didn't bat in that game. He has so far played nine Tests in addition to 17 ODIs.

I know that Murali holds the record for five-fors in Tests - but who holds the ODI record? asked Asela from Sri Lanka

The man with the most five-wicket hauls in one-day internationals is Pakistan's Waqar Younis, with 13. Muttiah Muralitharan comes next with eight, ahead of Glenn McGrath (seven), Lance Klusener, Saqlain Mushtaq and Wasim Akram (all six). For a list of the leading wicket-takers in ODIs, click here. You're right that Murali leads the way in Tests, with 53 five-wicket bags in 106 Tests - exactly one every two matches - well ahead of Richard Hadlee and Shane Warne, who have both taken five or more in an innings on 36 occasions.
