uwe-r. Not a bad rule of thumb, but 500 an innings is wishful. Duncan Fletcher set a target of 400 for the 2005 series as being their target first innings score, which more often than not meant someone getting a ton, he reckoned if you got 400 then you’d generally be in a strong position.
Cricket’s not just about centurions, it’s about partnerships – hopefully trotty can just bat and bat and let bell and Bairstow and Prior form partnerships along the way. If these 3 can average 60 or so per partnership, that’ll put us close to 300 which is a solid base.
