Responding to Jamaica's first innings overnight declaration score of 354 for nine declared at the Yorkshire Sports Club, Guyana tumbled to 214 all out, as off-spinner Blackwood and West Indies Under-15 leg-spinner Nelson both returned identical figures of four for 52.

At stumps, the Jamaicans had built their overall lead to a beefy 187, closing at 47 for one with Nick Blackwood on 17 and Courtney Allen on one. Guyana's innings suffered a crushing middle- and lower-order collapse. Opener Trevon Griffith stroked 69, with 10 fours and a six in a 147-minute stay at the crease but the Guyanese lost their last six wickets for a mere 11 runs from 203 for five.

When play resumed yesterday, Guyana began their reply after Jamaica's overnight declaration and Griffith, who drove pacer Gifton Wray for two elegant off-side boundaries, added 27 runs in 52 minutes on a flat track with Royan Fredericks. Fredericks (10) looked very tentative in his 32-ball innings and was bowled by left-arm pacer Romeo Dunka as he played over a full delivery.

Griffith took the fight to the Jamaicans with positive stroke play. The 17-year-old left-hander drove the pacers commandingly through the covers and disdainfully swept off-spinner Andre Creary for six as he dominated a 37-run stand with Jeetendra Sookdeo, who made 16.

Sookdeo looked uneasy against Nelson and after being befuddled by a succession of googlies from the 14-year-old, the left-hander edged a ball that bounced and spun away from him to slip and Guyana were 64 for two after the 50 was posted in 17.2 overs.
