England began building their slim lead over West Indies on day four of the first Test in Southampton after edging 54 runs in front - but lost Joe Denly cheaply before tea.
Denly had departed for 29 and handed Jason Holder a simple catch after clipping to mid-wicket, putting the pressure on stand-in skipper Ben Stokes to steady England's efforts at the crease.
Dom Sibley's wicket also fell after he brought up his half-century, moving across the stumps and glancing his shot fine down the legside. Shane Dowrich took the catch, but Zak Crawley, despite his initial wobble, helped calm down the hosts.
