Who said it had to hit the leg?;
1. Out LBW
The striker shall be out lbw in the circumstances set out below:
a) Striker attempting to play the ball
The striker shall be out lbw if he first intercepts with
any part of his person, dress or equipment a fair ball which would have hit the wicket and which has not previously touched his bat or a hand holding the bat, provided that:
(i) the ball pitched in a straight line between wicket and wicket or on the off side of the striker’s wicket, or was intercepted full pitch and;
(ii) the point of impact is in a straight line between wicket and wicket, even if above the level of the bails.
b) Striker making no attempt to play the ball
The striker shall be out LBW even if the ball is intercepted outside the line of the off stump if, in the opinion of the umpire, he has made no genuine attempt to play the ball with his bat, but has intercepted the ball with some part of his person and if the other circumstances set out in (a) above apply.
And I have the footage of that dismissal on video and on replays, the ball looked to be on its downward path when it hit Sachin and looked to be heading towards the top of the stumps. It certainly hit him in line too. If it was done on replays, I'd say it woud have had a fair chance of being given.
That said, if I was the umpire out on the field, I wouldn't have been able to give it out because I would have thought from that perspective, I woud have enough doubt to give it not out. But then, I'm not an international standard umpire.
Worst decision I've seen; Alan Donald to Geoff Marsh in the 1992 WC, first-ball of the innings. Donald bowled a quick short and wide ball and Marsh got the biggest edge on the cut you've ever seen. Was given not-out for some inexplicable reason by Brian Alridge. Not that it mattered; Saffies won the match easily.
