It's never too late to start really, as long as you have some grasp of the sport. I've only played one year of youth club cricket as well as a few years in the school team, but I'm probably good enough for my team now. Granted I play for the 3XI who are in the bottom league of the area, but I play with some pretty good players and I have fun.
I got picked primarly as a bowler, although that was my Dad talking not me. I said I was more of a specialist fielder, having only bowled 2 overs prior to this season, but now I'm probably one of our specialist bowlers. Don't really bat much, have only faced 3 balls this season (0*, 0*), but hopefully with a bit of practise in the nets I'll get a run
And Hamster, don't think you'll find many teams in Birmingham. Don't think they play much cricket there
