Marcus is a Legend!
Don't let's get carried away!
Re Castle I suspect he'll be back on the BBC when they finally show some tennis again but I think all these comms are freelance and follow the money. But it's possible that he's had criticism for his negative stance towards Andy so perhaps is being more circumspect. I noticed at DC that he accepted Andy had a case for not playing unlike that awful Frew Macmillan who said it was a disgrace.
