They have now have 60 points, 24 clear of second-placed Guyana. Though Jamaica will sit out the next round of matches with a bye, they are assured of finishing the preliminary round on top the standings.
This scenario opens up a race for the remaining spots in the final four, with each team still in with a chance of qualifying.
Despite holding second spot in the standings, Guyana will have to ensure they beat Trinidad and Tobago in the next round starting Friday to guarantee themselves a semi-final spot, as they sit out the last round with a bye.
The remaining teams all have access to 24 points as they will be fully engaged in the next two rounds.
T&T lie third on 28 points, Barbados are fourth with 24, Windward Islands have 16 while Leeward Islands and Combined Campuses and Colleges are both on 12 points and will need a virtual miracle to reach the last four.
Also in the next round, Barbados host Leeward Islands at Kensington Oval while the Windwards face CCC at the National Stadium in Grenada.
