Eoin Morgan described Alex Hales’ comeback century as an “unbelievable” innings as England beat West Indies by 186 runs at Kensington Oval to wrap up a 3-0 series whitewash. Hales returned after missing England’s last six white-ball matches with a broken hand to figure in a second-wicket stand of 192 with his fellow centurion Joe Root as the tourists piled up 328 all out after losing the toss on an occasionally awkward surface.
