Resurgent Jamaican Association shattered Caribbean rivals Spring Garden Cavaliers' dreams of an unprecedented hat-trick of titles this season by beating them by four wickets in the Commercial Cricket League's Twenty20 League Cup final at Shelly Bay.

With the league title already under their belts, Cavaliers, who swept into the Twenty20 final by trouncing Forties and BC Allrounders in June, were clear favourites to add a second crown this season – especially as the Jamaicans had to see off North Village first in Sunday's second semi-final.

But, inspired by their crushing 37-run victory over ten-man Village, thanks to pace bowler Kevin Abrahams' five-wicket haul, the Jamaicans made light of doing double duty on the day by edging defending champions Cavaliers with two balls to spare chasing 137, despite former Warwick batsman James Pace's fighting 71.

Cavaliers have found the Jamaicans, who finished fourth of the five teams, a thorn in their side this season, having to settle for winning draws in both league matches.

"This is a real feather in our cap after a poor league season," said a jubilant Glenmore Barrett, the Jamaicans' manager.

Three of Cavaliers' big guns failed with the bat and their depleted attack could not hold off the resolute Jamaicans, who owed their victory to an unbroken seventh-wicket stand of 59 between Ian Coke (18 not out) and Presley Millwood (32 not out) after openers Alleyne Francis and Wayne Lock were both run out for ducks.

Cavaliers also made a wretched start after being sent in, Donovan Livingston being trapped lbw by Coke (two for 30) for a second-ball duck and fellow opener Jeff DeSilva bowled by man of the match Abrahams (two for 23) for one.

Barry Richards was bowled by Junior Lindo, back after attending a funeral in Jamaica, for nine and skipper Dave Greenidge fell to Michael Campbell for two.

Number three Pace blasted five sixes and four fours in his 52-ball 71, adding 51 for the fifth wicket with all-rounder Craig Smith (21) as the pair helped guide their side to a competitive 136 for eight.

DeSilva did his best with the ball to keep the Jamaican batting in check, claiming four for 18, after Lindo (27) and Abrahams (33) revived the innings with a third-wicket stand of 54 following the loss of both openers with only five runs on the board.

Pace was entrusted with the final over but Coke and Millwood eased their side to victory.

"Our victory was down to a good all-rounder performance," said Barrett.

"We knew we had the potential. Making early inroads in their batting was spectacular for us and gave us momentum. I was confident we could get 130-odd to win.

"It was a big asset that we had an official umpire (Richard Austin) for both games," added Barrett , who is still trying to arrange a date for their annual Caribbean Cup showdown against Cavaliers.

"Their win over Village earlier in the day gave the Jamaicans a huge boost of confidence," admitted Cavaliers' Richards, who opened the bowling and saw his two overs go for 22.

"We thought 136 was a good score but we didn't bowl or field well – we dropped at least six catches, all dollies.

"They were the better team on the day.

"They played very well and had a lot of confidence. We might have been too confident – they surprised us. It wasn't our day."

Earlier, Jamaican Association's 111 from 19.3 overs proved too stiff a total for Village, who were restricted to 74 for eight as Abrahams scythed through their batting with five for 19 from four overs, with Coke chipping in with two for ten.

Skipper Francis (22), Lock (26) and Lindo (20) gave the Jamaican total early impetus, Randy Smith (three for 25), Dion Ball, Jr. (three for 28), skipper Allen Walker (two for 17) and Rudy Smith (two for 21) taking the Village bowling honours.

Village never recovered from losing openers David Scraders Ball, as well as Walker for ducks, Maurice Steede topscoring with 17.

"We congratulate Jamaican Association on their win and also on winning the tournament," said Walker.

"It is always good to show our league champions that those at the bottom half on the table are still capable of beating them."

Meanwhile, Cavaliers return to action this Sunday when they play BC Allrounders in a Knockout Cup preliminary round match at Shelly Bay.

The winners will face Jamaican Association while Forties meet Village in the other semi-final on August 22.

"We'll be back on track against BC Allrounders," added Richards. "They're going to suffer greatly."
