Prediction time: Cook and Jennings out by lunch with Ballance falling either just before or after lunch. Root and Bairstow to play like it is a ODI with a similar run-rate and to put on at least 75 between them but will fall before tea. The rest to fall before the Close Of Play with only Stokes and Ali making double figures, but less than 50 between them.
Or, Cook bats all day, Jennings lasts till just before lunch, with Ballance going just after Lunch. Root makes it to Close of play, England 345-2.
