I'm so pleased for all of them, but Brook in particular. He's really deserved his chance after scoring so heavily for Yorkshire.
There's little question that Bairstow will come back in once he's recovered (apparently he's hopeful for the Ashes). So it's potentially really unfortunate for Foakes that he was the only one who failed to make it off the toilet seat this morning. Could very easily slot Bairstow into Foakes' no.7 spot, and he's missed the chance to smash a score in this test.
What a crazily brilliant day.
