Guyana Amazon Warriors 108/9 in 20 overs (Ross Taylor 25; Mujeeb Ur Rahman 3-11, Fidel Edwards 3-30)
Jamaica Tallawahs 113/5 in 18 overs (Nkrumah Bonner 30*; Naveen-ul-Haq 2-35)
Incisive pace bowling from Fidel Edwards and the wily spin of Mujeeb Ur Rahman stifled Guyana Amazon Warriors on a sluggish surface as Jamaica Tallawahs completed their second win of the tournament.
The contest could not have begun on a more positive note for Jamaica with Edwards' red-hot yorker sneaking past the bat of Brandon King to rattle the woodwork on the very first ball of the match.
Edwards' blazing spell of bowling accounted for the scalp of the struggling Anthony Bramble in the Powerplay as well while Mujeeb got the important wicket of the in-form Shimron Hetmyer on the other end.
Hetmyer's dismissal, attracting doubts over the validity of the lbw decision, was followed by a sedate repair job from Nicholas Pooran and Ross Taylor.
Their resistance was undone by Mujeeb, who struck once again with a slider that knocked off the middle pole of Pooran.
A middle-order collapse triggered by spin twins Mujeeb and Sandeep Lamichhane derailed the little progress made by the Amazon Warriors.
At one point, the Chris Green-led side was in danger of creating the unwanted record of the lowest CPL total but they were able to avoid being bundled out as they crawled to 108-9 thanks to Naveen-ul-Haq's run-a-ball 20.
Jamaica's bright start in the first six overs was spoiled by a brief wobbly period where Ashmead Nedd and Keemo Paul provided crucial breakthroughs.
Skipper Rovman Powell and T20 basher Asif Ali were sent packing to the pavilion for single-digit scores leaving the lower middle-order with a steep task of overhauling the modest target.
Andre Russell and Nkrumah Bonner made sure there were no further slip-ups and did well to prevent a repeat of their previous battle when Guyana were successful in defending 118 runs.
Bonner finished the match with a touch of flair and aggression by smacking a boundary and a six off the bowling of Naveen as the Tallawahs romped home with two overs to spare.
