the coveted Commercial Cricket League double when they held off a spirited challenge from Lucozade Leg Trappers to win an enthralling knockout semi-final by eight runs at Somerset Cricket Ground on Sunday.

Watford's opponents in this Sunday's knockout final at Sea Breeze Oval will be Jamaican Association, who scored a comfortable 63-run win over West End Warriors in the other semi-final at the Bailey's Bay ground.

This Sunday will also see the inaugural challenge between a Commercial Select XI and a Devonshire Rec. XI, a 50-overs match at Police Field starting at noon.

An unbeaten 51, containing four boundaries, by Norman Godwin and useful knocks by David Gibbs (32), Arthur Dublin (30) and Ian Coke (20) laid the foundation for Jamaican Association's imposing 215 for nine after they were sent in.

Vernon Eve and Leon Eve each took two wickets.

Warriors slumped to 28 for five but Ronald Gibbons, their gifted 21-year-old leading batsman who seems certain to be snapped up by a Premier club next season, helped give the total an air of respectability by hammering five fours and three sixes in a swashbuckling knock of 49.

Warriors were finally dismissed for 152 in the 33rd over. Gibbs was the pick of the attack with three for 38 -- including the wicket of Gibbons -- and there were two wickets apiece for Michael Campbell and George Fisher.

Watford, who twice narrowly beat Lucozade in the league, owed Sunday's success to a flurry of runs in the closing overs of their innings, spearheaded by Troy Berkeley who smashed two sixes -- one broke the windscreen of team-mate David DeSilva's mother Mary's car -- and three fours in a whirlwind knock of 38.

Terry Ward, who stroked eight fours and a six in a chanceless innings of 66, also perished in the late-order charge as Watford lashed 73 runs in the final nine overs to reach 176 for nine in their allotted 40 overs.

Watford had made a disastrous start after being sent in, Dave Wright having Michael Corday well caught in the slips by Pete Norris off the first ball of the innings.

Clyde Best (30) and Ward repaired the early damage, cautiously adding 55 for the second wicket as Watford were pinned down by Wright (two for 11) and Graham Strange, masters of line and length, who conceded only 18 runs between them in 16 overs.

Roddy Moore, Lucozade's most successful bowler, picked up three late wickets for 35 while David Outrim chipped in with two for 22.

Although Pete Norris went for five with the total 28, well caught low down at slip by Best off medium pacer Ray DeSilva, skipper Gary Knight carried the fight to the Watford attack, adding 36 for the second wicket with Strange before unluckily kicking the ball on to his off stump as he tried to avoid playing on to Blake West (two for 38). Knight struck two sixes and a four in his 31.

Lucozade, well placed at 115 for three from 26 overs, lost their way after Strange attempted to pull the first ball of Terence Corday's second spell, a short delivery which gained little height, and had his off stump uprooted.

Strange hit five fours in his 39, including a free hit after a Berkeley delivery ballooned out of his hand and stopped at short mid-wicket.

Three runs later Mark Finnigan, who hit four fours, went for 20 when well caught at long-off by Ray DeSilva and at 141 David DeSilva held a steepling catch off Wright on the deep mid-wicket boundary.

James Broadbent, with 28 not out, kept his side in the hunt but Lucozade failed to match Watford's late assault and added only 46 runs in the final nine overs, including five singles in the final over from Ward, to close at 168 for eight.

"It was disappointing to lose,'' said Knight afterwards. "That's three times we've lost to Watford now. Troy did it really with that knock of 38. We were too cautious in the middle of our innings.'' The Commercial Select team for Sunday's match is (from): Gordon Campbell (captain), Rohaan Simons (both Forties), Grant Tomkins, Rohan Moore (Police Recreation Club), Graham Strange, Dave Wright (Lucozade Leg Trappers), Jerry Callender, Randy Liverpool (West Indian Association), Derek Bell, Mike Levon (North Village), Ronald Gibbons, Vernon Eve (West End Warriors).
