Edited sentence: For example, Gary Sobers was a world-class all-rounder and also a world-class specialist batsman; but he was not a world-class bowler, albeit a very good one.In a career spanning 44 years, his batting average was 39.45 at first class level, an average undoubtedly dragged down by playing into his late fifties.This assessment is indisputable for Grace is the only player in cricket's history who can claim to have been world-class at both batting and bowling as specialist activities; rather than being world-class because of all-round ability per se
