West Indies cut England's lead in second Test to 219 runs by stumps on day three as Kraigg Brathwaite and Jermaine Blackwood score centuries.
Brathwaite has borne some criticism over the years for batting too slowly, but here he once again proved his worth as he brought up his century off 274 deliveries.
In this game, Blackwood made his third century in a 45-match long career that has spanned almost eight years.
A sign of England's frustrations came in a heated exchange between Blackwood and Ben Stokes, with the umpires stepping in.
