Neil McGarrell's left-arm spin tormented the Windies-B batsmen. The former West Indies spinner bowled 34 overs for a mere 28 runs and snatched four wickets in the process.

With a deficit of 191 runs, they fell for 187 but got as far thanks to a thunderous half-century from last man Dwight Washington who slammed two fours and half-a-dozen enormous sixes in his 58 which was his contribution to a last-wicket partnership of 66 with Ryan Austin (13).

The day started quite scarily for Guyana, needing full points to stand a chance of qualifying for the semifinal rounds, when dark clouds hovered over the ground, damp from overnight and early morning rain. Play started twenty minutes late and the Windies-B, starting on 51 for 2 looked up for a fight to save the game. Ryan Ramdass, the Guyanese right-hander moved from 25 to 43 then to his dismay, umpire Zainol Macoon raised his finger in a flash when a lighthearted jovial appeal went up for a caught behind, though the batsman clearly played away from the ball. Several of the Guyanese players were surprised by the decision, but Ramdass had to go after facing 128 balls and striking four fours.

From 75 for 3 the score slipped further to 76 for 4 when wicketkeeper batsman Patrick Browne went lbw to eventual man-of-the-match Mahendra Nagamootoo (2 for 72) for a duck.

Lunch was taken with the score on 85 for 4 but shortly after the interval Jamaican batsman Danza Hyatt (20), who batted throughout the first session with restraint and caution, was very surprised when he was given out lbw as his front foot was way down the track as he played defensively but missed and was taken on the pad.

Nagamootoo got that wicket to end with match figures of 7 for 172 to nicely complement his 58 in Guyana's innings of 419. Kenroy Williams (1), the Barbadian all-rounder, was taken comfortably behind by wicketkeeper Vishal Nagamootoo for McGarrell to pick up his fourth wicket of the innings and the sixth of the game.

Austin Richards was bowled by one that kept extremely low and beat his defensive bat. Richards made 12 and the score was then 106 for 7 with Guyana scenting victory well before tea.

Three runs later Antonio Thomas, one of six Bajans in the Windies-B team drove the ball just wide of mid on and ran suicidally down the track. The result was obvious, he was run-out for three to make the score 109 for 8. Then as the Guyanese were looking to wrap up the tail they were delayed first by solid defensive play then by an unexpected onslaught.

Jason Bennett (8) hung around for three quarters of an hour with Austin and took the score up to 121 before he prodded forward and was caught at silly mid-off by Sewnarine Chattergoon, the ball hitting the pad then edging his bat as it went to the fielder.

Last man, the towering Jamaica Washington then proceeded to enjoy himself, hitting cleanly and powerfully in registering his highest first-class score and his only fifty at this level.

He took a mere 39 balls to reach the landmark, entertaining the large crowd with three consecutive sixes off Nagamootoo, the last of which ended out of the very large ground.

Before that flurry when he took 19 runs off Nagamootoo and hit him out of the attack, he had hit one six then reached his fifty with another massive whack which sent the Ramnaresh Sarwan-bowled ball sailing even further out of the ground.

Five of the sixes, in Washington's run-a-ball innings, were hit over the long-on region, the other went over long-off and the crowd, starved for some batting action, were gallivanting in merriment.

In their 66-run partnership Austin contributed only 8 and was left as an admiring spectator as his partner took on the spinners, something which none of the Windies-B batsmen did in either innings.

With the tea session extended by 30 minutes to allow Guyana the opportunity to end the game, it looked as though they would need to bat a second time after Washington and Austin took the score to within 4 of the deficit.

But just before 15:00 hrs Rayon Griffith did what the spinners were unable to do. He bowled Washington, flattening his middle stump to prevent Guyana from batting again and end a fantastic lesson in power hitting by the tail-ender.

Guyana with two consecutive victories after beating Trinidad & Tobago in the last round now move to Bourda to take on Kenya in another must-win game while the Windies-B travel to Grenada where they will face the Windward Islands.

Guyana have now sneaked past Windies-B (27 points) on the points table, and both teams will be dependent on the results of the other three final round games if they are to go through to the semifinals.
