Some statistics, like Bradman's average and the number of centuries Tendulkar has made are known to pretty much every cricket buff. But The List will bring you facts and figures that aren't so obvious, adding fuel to those fiery debates about the most valuable middle-order bat, and the most useless tailender. If there's a particular List that you would like to see, e-mail us with your comments and suggestions.

Only 36 hat-tricks have occurred in 1783 Tests and a mere 20 in 2321 ODIs. They are rare events that trigger supreme adrenalin rushes, and apart from the wild excitement a hat-trick provides, it is of immense value to a team. But how do you measure a hat-trick's `value'? The List looks at heavyweight hat-tricks, measured in terms of the sum of the averages of the batsmen dismissed.

Irfan Pathan's hat-trick in the ongoing Test against Pakistan at Karachi was not just the first in the first over of a Test, it was also the highest in terms of total averages of the batsmen dismissed (130.18: Salman Butt 34.27, Younis Khan 46.04, Mohammad Yousuf 49.86). For sheer weight of runs, Glenn McGrath's three-in-three that included Sherwin Campbell, Brian Lara and Jimmy Adams (total runs 11,388) is the highest. McGrath's hat-trick was special because Lara was his 300th Test wicket and he had predicted reaching 300 wickets with the scalps of Campbell and Lara.

Frederick Spofforth was the first to perform this feat when his 13 for 110 helped Australia rout England by ten wickets at Melbourne in 1879. Taking a hat-trick is tough enough but to do it twice in a match is probably a once-in-a-blue-moon feat. Jimmy Matthews took hat-tricks in each innings (both on the same day) against South Africa at Old Trafford in 1912 and Tommy Ward was his third wicket on both occasions.

Apart from Matthews, Hugh Trumble and Wasim Akram are the only other bowlers to have taken a hat-trick on two occasions. Akram's hat-tricks came in consecutive Tests against Sri Lanka at Lahore and Dhaka during the Asian Test Championship in 1999. Trumble was the first of two bowlers to take a hat-trick in his last Test. The other was Geoff Griffin who became the first to take a hat-trick at Lord's in just his second Test. But in the course of the match, he was no-balled eleven times for throwing and never played another game.
