Sibley has bee totally competent. Let’s hope this is start of a great test career. Talk is declaring 10 overs post lunch.
I'd agree with that, get them to do a little bit more in the field whilst Curran and Sibley tee off, 10 overs or the next wicket, whichever comes first. This is about grinding their face in the dirt more than adding anything to the target, it's the sort of thing Australia, South Africa and India do to teams in this situation.
Almost a perfect session for England
I'd go a bit further and say this is almost a perfect 3rd innings.
