If Afridi was injured Sanga would have allowed him a runner but he wasn't so he didn't allow him one. Remember the champions trophy in SA last year where England were playing South Africa and when Graeme Smith asked Strauss for a runner he didn't oblige.In my opinion he should have offered him but obviously Sanga didn't want to lose the match, so instead of whining about sport spirit and runners just move on. I'm sure if any of the lankans were in the same scenario Afridi wouldn't have offer a runner too.
