Laxman's 281, vs Australia
It could probably be seen as a match saving innings but from this magnificent inning, Laxman (with the help of Dravid) did put us in a position where we had a chance to win the match and the rest was just history. Laxman's innings was characterized by his audacious wrist work and timing. Of course I was only about 7 at the time when the match was played and probably didn't appreciate how significant his innings really was, but it really was one of the greatest moments if not the greatest moment in world cricket in the eyes of an Indian.
So share some of the greatest match winning innings that you have been able to witness!
