TITLE-HOLDERS Jamaica stretched their lead to a commanding 169 runs after a disciplined bowling performance helped them bundle out Guyana for 126 during yesterday's second day of the West Indies Cricket Board four-day semi-final match at Sabina Park.

Batting a second time, Jamaica, hunting an historic fifth consecutive regional first-class triumph, closed on 99-3, thanks to side-lined West Indies batsman Xavier Marshall's unbeaten 54. Jamaica made 196 in their first innings.

Scores: Jamaica 196 (79.2 overs) and 99-3 (26 overs); Guyana 126 (61.4 overs).

Captain Tamar Lambert, not out on one, will resume with Marshall when play continues at 10:00 o'clock this morning.

Marshall, who is eyeing his maiden first-class hundred, rode his luck well on a pitch that has offered a bit more to the spinners than it did on day one. The 26-year-old has struck six fours and a six from 84 balls.

Brenton Parchment (22), Donovan Pagon (eight), and debutant Jermaine Blackwood (seven) were the Jamaican batsmen who fell yesterday. Spinners Veerasammy Permaul, Devendra Bishoo as well as pacer Brandon Bess have taken one wicket each.

Guyana, resuming on 14-1 after Trevon Smith was dismissed late on the opening day, lost the overnight pair of Chanderpaul Hemraj and Leon Johnson in quick succession as the Jamaican seam attack generally held to a steady line and length.

With just one run added to the total, Hemraj (three) edged Andrew Richardson's delivery and was caught by Brenton Parchment at slip.

It was soon 21-3 when Johnson tucked a delivery from David Bernard into the hands of Odean Brown at square-leg.

Narsingh Deonarine and Assad Fudadin — Guyana's top run getters this season -- added 20 runs for the fourth wicket before Bernard and left-arm seamer Sheldon Cotterell sent the pair back to the pavilion.

Deonarine (12) got an edge to a perfectly angled delivery from Bernard and was caught by wicketkeeper Horace Miller, while Cotterell trapped Fudadin (14) leg before wicket with a quick, full-pitched ball to leave Guyana reeling at 66-5.

Wicketkeeper/batsman Derwin Christian was run out by Blackwood after he and captain Shivnarine Chanderpaul attempted a sharp single to the athletic 20-year-old at point.

Bernard, in the middle of a testing spell, got his third wicket of the innings when he dismissed Permaul through the lbw route with the score at 90-7.

Left-arm spinner Nikita Miller, who was belatedly introduced by Lambert, almost sent back the usually solid Chanderpaul, but Parchment was unable to hold onto a difficult chance at slip when the batsman was on 40.

Miller, however, stuck to the task and accounted for the wickets of Bishoo, Beaton and Bess as Guyana were rolled over for 126.

Miller ended with 3-16, while Bernard took 3-35. Richardson, who bowled a lively spell early in the day, finished with 2-18.

Chanderpaul, warming up for the Test series against the touring Australians, remained unbeaten on a typically patient 47.
