Joe Root withheld judgement on where his unbeaten 182 in Grenada ranks among his six Test centuries until the end of the match.
Having magnificently scored his first overseas format hundred on day three, Root advanced from 118 to his second-best Test total.
The classy right-hander was denied the chance to match or beat his 200 not out versus Sri Lanka at Lord’s last year when last man James Anderson was surprisingly run out by not sliding his bat in.
That left England with a first-innings lead of 165, but centurion Kraigg Brathwaite and Darren Bravo ate into the advantage with a second-wicket stand of 142.
By stumps West Indies were 202 for two, 37 ahead, going into the final day of this second game of three with the series level.
Questioned about his innings, Root told ecb.co.uk: “It’s obviously pleasing to make a big hundred, but you’ll have to ask me at the end of the game. If we get a result out of the game, it’ll mean a lot more.”
Although the tourists toiled on a lifeless pitch for two wickets in just over as many sessions, Root sees some hope of putting West Indies under pressure tomorrow.
“I see it pretty much in the balance,” added the 24-year-old, who blogs exclusively for ecb.co.uk.
“It’s a very flat wicket, not very responsive for the bowlers. We’re going to need a very good session tomorrow morning, up front.
“If we can get a couple of early wickets you never know we might have a game on our hands, but it’s a very flat wicket at the moment.”
Root gave his take on Anderson’s bizarre dismissal, when the number 11 looked to be comfortably completing a second run only to not run his bat in as Jason Holder grabbed a high throw from deep midwicket and broke the bails.
Root’s immediate thought was that he was responsible for a second run-out, having earlier changed his mind over a second run that led to Chris Jordan being dismissed.
On the wicket of Anderson, who soon partially make amends by forcing Devon Smith to play on, he explained: “We were both pretty annoyed because we both thought it was our fault. Obviously I wasn’t looking and I thought I’d sold him down the river like Chris earlier on.
“I was a bit frustrated that we could have built on that partnership and got a bigger lead. We got back to that changing room and (I) realised why Jimmy was quite annoyed as well.
“It’s one of those things, it would have been nice to get a bit more of a lead, but we came straight back out in that 20-minute period and got a wicket so it’s part of the game I suppose.”
