The Risers found it hard from the start after winning the toss and electing to bat first.
Delbert Gayle (27) and Nicholas Lewin (15 not out) were the only batsmen to reach double figures as pacers Ojay Shields (2-9 off two overs) and Andel Gordon (2-13 off two) combined to restrict the Risers to a modest 72-6 off their 10 overs.
Jamaica Scorpions all-rounder Alwyn Williams with 30 not out and Damani Sewell with 15 not out then helped the Stars reach 71-1 in the eighth over before rain ended proceedings with the Stars comfortably 19 runs ahead of the Duckworth/Lewis par score.
West Indies opener John Campbell earlier made 20 for the Stars who now have four wins from eight matches.
After starting Friday’s day three 259-6 off 73.1 overs, the Scorpions ended up being bowled out for 331 in 91.2 overs, a lead of 24 runs.
Peat Salmon was instrumental in helping the Scorpions establish a lead with a 44-ball 45 including four fours and two sixes.
17-year-old Zishan Motara, who entered the day with four wickets to his name so far in the innings, added three on day three to finish with career-best figures of 7-108 off 31.2 overs.
Facing a deficit of 24, the CCC had a horrendous showing with the bat in their second innings, being dismissed for just 87 in 30.4 overs.
Kirstan Kallicharan led the way with the bat with 29 against some excellent bowling from the Scorpions.
Peat Salmon with 4-12 from seven overs, Gordon Bryan with 3-19 from nine overs and Abhijai Mansingh with 2-35 from 8.4 overs were the main destroyers for the hosts.
Needing only 64 for victory, Scorpions openers Chadwick Walton and Carlos Brown wasted no time, needing just 9.3 overs to reach 69-0 and secure the Scorpions’ first West Indies Championship win in two years.
Walton followed up his 163 in the first innings with 46* while Brown, who hit 48 in the first innings, finished 19*.

The day started with the Kings losing to the Middlesex United Stars in a super over.
The United Stars win the toss and elected to field first, restricting the Kings, albeit with a number of changes to their team, to 85-7 off their 10 overs with Kenroy Williams (22) and Xavier Burton (17) being the main scorers.
Tyrone Daley was the pick of the bowlers for the United Stars with 2-14 from his two overs.
Top scores of 38 not out from captain and West Indies opener John Campbell and 21 from Jamaica Scorpions all-rounder Alwyn Williams then allowed the United Stars to match the Kings total reaching 85-6 off 10 overs.
The same pair along with Daley then combined to post 13-1 in the super over before Ojay Shields restricted the Kings pair of Jeavor Royal and Brad Barnes to eight without loss to secure the win.
The Surrey Royals got the better of the Cornwall Warriors in the second match of the day by nine wickets.
The Royals restricted the Warriors to 86-6 off their 10 overs after winning the toss and choosing to field first.
Captain Damian Ebanks (25), Damion Bryce (21 not out) and Kerry Holness (18) were the main contributors for the Warriors against an excellent 2-8 off two overs from Jamaica Scorpions pacer Nicholson Gordon.
The Royals then successfully got to 87-1 off 8.1 overs thanks to 61 not out off 29 balls from wicketkeeper/batsman Romaine Morris.
With the league stage now completed, Wednesday will see the Cornwall Warriors and the Surrey Risers contest the fifth-place playoff, while the third-place playoff will be an all-Middlesex affair with the Titans taking on the United Stars before a champion is crowned on Thursday when the Surrey Royals and the Surrey Kings battle it out.
The hosts ended the day 259-6 from 73.1 overs, trailing CCC by 48 runs on first innings.
38-year-old Chadwick Walton, playing his first season of first-class cricket since 2019, led the way for the Scorpions with a masterful 168 off 245 balls including 16 fours and five sixes.
Walton shared in a 169-run opening partnership with Carlos Brown, who was the Scorpions’ next highest scorer with 48.
No other batsman was able to make any meaningful contribution as 17-year-old leg-spinner Zishan Motara ripped through the bulk of the Jamaican batting on the way to figures of 4-69 from 22.1 overs.
Earlier, CCC ended up being bowled out for 307 off 97 overs, adding a further 47 runs to their overnight score.
Jonathan Carter finished 135* off 217 balls against three-wicket hauls from Gordon Bryan and Ojay Shields and two wickets from Abhijai Mansingh.
