I reckon you could have the crowd of 20000 at the WACA on the field. Steve Smith will still somehow find a gap for four. #Ashes #SteveSmith

If Steve Smith tells you to review think it best to ignore, not really his strength!! #Ashes

Steve Smith is the world's best batsman - by a country mile. Nobody in modern history has averaged more than 60 in Test cricket.

Why would you bowl there to Smith? And by ‘there’, I mean ‘at a cricket ground’. #Ashes

Dear Promising 17yo English Quicks,

Wouldn’t you rather be 93mph for 4 years before breaking into pieces than 80mph for 12 years while breaking all our hearts? Be Top Cat, not Officer Nibble. A lot of people’s vicarious sense of self-worth depends on it. #Ashes

Life supports me like England's lower order supports their batting lineup.

Bairstow 'butts' his helmet in celebration of his 100. Wonderful moment for him after a tough tour
