Great game cricket!!!
Trouble is that to get a decent sports scholarship you tend to have to be doing extremely well in a sport.
Suspect it might not be so competitive in rarer sports but cricket is very popular and there are great numbers of lads playing for clubs, districts and counties.
Most scholarships are for relatively small amounts of money off the fees (10%0 - have just looked at some of the London schools (St Paul's, Highgate ) - and they only offer academic / music scholarships However City of London offer team sports scholarships so they might be worth looking at.
