Nottingham: Eoin Morgan hit his first test hundred as England took charge against Pakistan on Thursday by reaching 331-4 at stumps on day one of the first test.
Morgan, previously considered a one-day specialist, underlined his credentials as a test-class batsman with a stylish 125 from 182 balls that included 18 fours and a spectacular six to bring up his century at Trent Bridge.
Paul Collingwood made a more measured 81 not out from 168 balls, with 11 fours, batting through the evening session with Morgan for an unbroken stand of 213 - an England record for the fifth wicket against Pakistan.
Mohammad Aamer took 3-39, but Pakistan's bowlers toiled after having England in trouble at 118-4 early in the afternoon session.
England chose to bat first after winning the toss, despite overcast conditions that aided Pakistan's opening bowlers.
The host moved tentatively to 22-0 in the fifth over when captain Strauss, on 15, got an inside edge to a delivery from Aamer, only for wicketkeeper Kamran Akmal to drop the simplest of catches.
However, Aamer got the wicket his bowling merited in the ninth over, when Cook, who looked nervous throughout his 26-ball innings of eight, nicked an away swinger to Imran Farhat at first slip.
Trott was on 13 in the 20th over when he was given out lbw to Danish Kaneria, but with the umpire decision review system being used for the first time in England, Trott instantly asked for it to be reviewed.
Television replays proved Trott had got his bat to the ball and umpire Asoka de Silva's decision was overturned.
Three overs later Akmal partially atoned for his earlier error, when he caught Strauss off Aamer, but Pietersen survived a testing spell with Trott to see England through to lunch without further loss.
Pakistan wasted the two referrals it is allowed per innings in the first four overs of the afternoon session.
De Silva was twice vindicated, as the cameras upheld his decision not to give Pietersen lbw to Asif in the 29th over, and his judgment that the same batsman hadn't touched the ball when Akmal claimed a catch in Asif's next over.
However, Pietersen's unhappy innings ended after 29 balls when he played on to Asif for nine in the 33rd over.
Trott (38) was lbw without playing a shot to Aamer in the following over and although he again referred the decision, this time third umpire Marais Erasmus agreed with Tony Hill's initial ruling.
In the 36th over Morgan edged a ball from Aamer behind and Pakistan celebrated what they thought was a wicket.
When Morgan was given not out Pakistan was unable to review the decision, but there was then a chorus of booing from the crowd as the big screen showed the ball had bounced before Akmal had caught it.
England's progress was painfully slow until Collingwood hit fours from successive Umar Gul deliveries, both through the covers, in the 44th over.
Morgan's confidence grew and he began sweeping and reverse sweeping the spinners, while Collingwood played the anchor role, as both men survived to the tea interval.
Morgan brought up his first ever test half-century, from 81 balls, with a single off Kaneria in the fourth over of the afternoon session.
Collingwood had advanced to 48 when he survived thanks Akmal's second major error of the day in the 71st over.
The batsman charged down the wicket looking to hit Kaneria out of the ground, but missed the ball completely, only for Akmal to fumble an easy opportunity for a stumping.
Two deliveries later Collingwood glanced a shot to fine leg for three to bring up his 50 from 114 balls.
Morgan was on 78 when De Silva ruled him lbw to Kaneria, but he successfully appealed against the decision and brought up his century in superb style by smashing Malik for six over long off in the 80th over.
