Centurions frustrate England

West Indies' fifth-wicket duo ensured the tourists suffered a fruitless first session on the fourth day at Queen's Park Oval to all but end their victory hopes. Two post-lunch successes, including that of Nash for 109, almost certainly came too late to make an English win possible.

West Indies were 494 for six, with Chanderpaul unbeaten on 122, in the second hour of the afternoon.

To add to their frustration, England were also controversially denied the scalp of Chanderpaul for 92 after Australian umpire Daryl Harper originally gave the Guyanese batsman out caught behind off off-spinner Graeme Swann.

Chanderpaul challenged the decision with the home team's final referral and it led to Harper altering his decision after consultation with third official Aleem Dar.

England arguably had a right to feel harshly treated given the guidelines of the umpire review system being trialled in this series state there must be compelling evidence the original decision was wrong for it to be overturned.

Television replays cast doubt as to whether the ball had taken the edge but were not conclusive.

Stuart Broad had struck in the previous over, with his first delivery of the afternoon session after switching ends, when Nash sliced straight to Paul Collingwood, stationed as the wider of two slips.

England's second success was delayed for another 10 overs, however, and came when Ryan Hinds got carried away with his counter-attack. One ambitious heave too many resulted in Swann beating him in the flight and wicketkeeper Matt Prior completed a smart stumping.

Before lunch, English frustration spilled over when fast bowler Broad was spoken to by Harper after appearing to show dissent in the eighth over of the day. Broad was called for a wide by Harper upon sending a bouncer down to Nash from around the wicket and expressed his displeasure at the decision.
