Missing a trick a little here Engand. Clarke is an excellent player of spin and is well out of nick. So why on earth would you bowl Moen and Root.
We've only got 10 overs left in the innings, don't give him an easy ride. Get Broad and Anderson on and try and knock him over, keep the Skippers confidence down. We're effectively letting him have a centre wicket net session. If they're worried about Anderson creating rough for Lyon then bowl him from the Nursary End.
Also takes longer to bowl the overs than them just milking the Spinners for 5/7 runs an over.
