West Indies coach John Dyson, meanwhile, admitted his side were focused on preserving their lead in the series.
"We are trying to get the opportunity to win but obviously we are not going to totally make the pace of play," he said.
"We are in the position we are in and we are quite happy to maintain that position.
"It was a difficult day. The wicket was very slow, but we had a reasonable day. It's a reflection of the pitches - they have offered very little for the pace bowlers and spinners."
He defended the decision to drop front-line spinner Sulieman Benn in marked contrast to England's thinking.
"It was decided that on two occasions on dry, flat wickets Sulieman didn't really go through the England batting. He did in Jamaica but not since, so we decided on this occasion to go for the extra batsman," Dyson explained.
