If this test were the decider in an Ashes series, Keston Jennings, Alex Lees and Rory Burns would all better options to have opened in this test but given the situation in the series, there seems little point bringing back one of the over 30s who have demonstrated they aren't good enough at this level.
Rob Yates looks the best of the younger openers on the county circuit to me and is having a good season. hasib hameed is also playing well again although probably not the dynamic the current set up would go for
