Spring Garden Cavaliers cracked open the champagne after clinching their first league title with a match to spare, despite failing to beat rivals Jamaican Association for the second time this season, while Simon Jones' maiden century helped confirm defending champions Forties as runners-up.

Cavaliers' seven points for their winning draw carried them 11 points clear of Forties, who beat North Village by 149 runs with six balls to spare, with one round of matches remaining before the Cup Match weekend break.

It is Cavaliers' first Commercial Cricket League championship since changing their name two years ago from West Indian Association, who won the title in 1996.

Cavaliers remain odds-on favourites to complete an unprecedented sweep of the three main titles, having already booked their place in next month's League Cup Twenty20 final in which they will face either Jamaican Association or Village. First round of the knockout, the third leg, will be held on August 8.

Cavaliers' jubilant skipper Dave Greenidge said: "One down, two to go."

A fourth century partnership of the season between irrepressible openers Jeff DeSilva and Donovan Livingston, who both fell in the 80s, laid the foundation for Cavaliers' 269 for five after being sent in at Shelly Bay but Jamaican Association made a spirited reply, closing on 205 for six, with skipper Alleyne Francis and Kevin Abrahams both hitting half-centuries.

DeSilva, who broke Lionel Cann's league record earlier in the season, struck 12 fours and two sixes in his 78-ball 87, while Livingston's 84 from 99 balls included seven fours and two sixes, the pair adding 125 for the first wicket.

Craig Smith, who also took three wickets, joined in the run spree, hitting seven fours and a six in his unbeaten 32-ball 51. Pick of the Jamaican attack were skipper Ian Coke (two for 55 from ten overs) and Abrahams (two for 78 from 13).

In reply, Francis, who hit five fours in his 51 before being run out, and Wayne Lock (36) gave the Jamaicans a handy start, adding 59 for the first wicket. Michael Campbell made 23 before retiring, and Abrahams, whose unbeaten 51 included four fours and three sixes, kept Cavaliers at bay, despite Smith's three for 35 from 12 overs.

"Jeff and Donovan yet again provided the excellent start we have come to expect, their fourth century partnership in seven league games this season, having scored 936 runs between them," said Cavaliers' spokesman Richard Foulds.

"They average 87 for the first wicket. Jeff was again in sublime form. You know you've had a great season when you score 87 and your average goes down!

"After Jeff was out Donovan put his foot on the gas and Craig also reached a half-century with his usual aplomb. With only a winning draw necessary to secure the league title, we felt the total was always going to be enough, but Jamaican Association made us work for it, and were not about to let us off without a fight."

Forties maintained this season's domination over North Village – their nemesis last year – with a crushing win at Garrison Field where both teams played one short.

Forties posted 260 for three declared from 40.2 overs after being sent in, 160 runs coming from the final 18 overs, as Jones and Ernest McCallan featured in a third-wicket stand of 150. Palithapushpa Kumara rattled up 28 from 11 balls.

Forties reduced Village to 54 for seven in the 19th over but skipper Allen Walker (15 from 81 balls) mounted a rearguard action, first with Reggie Benjamin (26 from 43) and then for the final wicket with 12-year-old Gayon Burrows (one not out from 18). Opener David Scraders made 23.

"We were afraid we had left the declaration too late but luckily took the last wicket with six balls to spare," said skipper Gordon Campbell.

Jones' 100 not out from 118 balls included eight fours and a six while McCallan's swashbuckling 67-ball 87 against his former club contained eight fours and three sixes.

Incisive early swing from Blake West and Yatin Gawas had Village on the ropes, West finishing with three for 32 from 12 while Campbell chipped in with three for 12 from seven. Anton Fernando took two for 15 from eight.

Jones said: "It wasn't the most free-scoring knock of all time – but it's great to get a century at last.

"It took a while to get going but batting with people like Mugsy (McCallan) and watching him hit four after four took all the pressure off.

"I had hit a couple of 60s and 70s back in the UK but had never seen it through before Sunday.

"Playing in the heat and humidity up at St. George's left me feeling like a wreck afterwards but it was a good win for us.

"It was nice of the skipper to let us bat a few extra overs at the end so that I could bring up the three figures."
