England faced trying times early in its first day-night test, needing a 69-run partnership between Alastair Cook and captain Joe Root to recover from two West Indies strikes on Thursday (Friday NZ Time).
After winning the toss on a handsome sunny day of the first ever day/night test match in England, Root and Cook lead the way for the hosts with brilliant hundreds.
Former captain Cook brought up his fifty shortly before lunch and Root soon followed him to the milestone, posting a half-century for the 11th test in a row to equal the record in five-day cricket.
The West Indies trailed England by 470 runs at stumps with nine wickets in hand.
The fifth ever day-night test, and first in England, was expected to offer the touring side their best chance of an upset but the hosts are now in a dominant position to take a 1-0 lead in the series.More news: South Africa border officials on alert to prevent departure of Mugabe's wife
Alastair Cook's double century ensured West Indies continued to struggle in the inaugural day/night Test in England at Edgbaston.
"It's something we did well in the previous two games against South Africa and again today". Anderson already has a scalp under his belt; removing Kraigg Brathwaite for no score.
But by that stage both Cook and Anderson, England's leading Test run-scorer and wicket-taker respectively, had struck telling blows.
This fixture, the 50th Test at Edgbaston, is the first match to be played with a pink-ball in England.
But before falling lbw on DRS to Roston Chase (four for 113) - pushing to leg and missing - he had spent nearly nine and a half hours at the crease and hit 33 fours from 407 balls.More news: Sierra Leone mudslides death toll now above 400, United Nations says
Cook batted through the day for his unbeaten 153, sharing 248 with Root, who made 136, as England hit 348-3 at Edgbaston.
The reception at the top table is beginning to wear off for Westley, following his inconclusive succession of middling scores so far - the latest his least productive to date after he played across and missed a straight ball to be lbw to first-change Miguel Cummins on DRS.
Cook then went to his 200 when a misfield by Kyle Hope on the third man rope allowed the ball to trickle through for the opener's 30th four in 339 balls. But he lost new partner Ben Stokes early in the second session when England's vice-captain, looking to move things along, was caught reverse sweeping to Chase on 10.
Cook, who was replaced as captain this year, showed his huge worth as a batsman alone and had his career-best score of 294 in sight.
For the second time this innings, the West Indies had to review a not out decision by South Africa's Marais Erasmus to get a wicket.More news: Trump Administration Agrees to Uphold Key Subsidies Paid to Insurers Under Obamacare
