This has always bothered me. Whn a batsman gets to ffity it's a nice little milestone and he raises the bat to the crowd. But if he manages to get to a hundred, it's erased from the 50s column. I mean, it's still a 50+ score, so why should it be erased from existence? It doesn't happen with 100s... (ie) when a guy gets to 200, it isn't erased from the 100s column and put into a separate one for doubles. Why the discrimination against 50s?
