Colombo Kings rode on the back of a scintillating half-century from Dinesh Chandimal and a blistering cameo from Andre Russell to ace their chase against Jaffna Stallions.
Chandimal began Colombo's innings briskly before settling into his groove and anchoring his side's successful journey towards the 149-run target.
Braving through the loss of Laurie Evans and Daniel Bell-Drummond in quick time, Chandimal and skipper Angelo Mathews combined to diminish the effects of the early damage.
Mathews, however, found it difficult to gain fluency and ultimately perished off a superb piece of fielding from 38-year-old Shoaib Maik.
The veteran all-rounder jumped on the edge of the long-off boundary rope but was unable to find the right balance as the ball threatened to evade his grasp. He then sensationally parried it back in the playing area and dived back to pull off a blinder to end Mathews' stay at the crease.
Colombo's innings was injected by an unadulterated dose of aggression from the powerful Russell, who initially took time to launch his typical meaty slogs.
He spanked three sixes and two fours in his 20-ball 32 that eventually decided the course of the match.
Jaffna could not make more breakthroughs as Chandimal fittingly hit the winning runs to bring an end to the opposition's unbeaten run.
Earlier, Qais Ahmad and Dushmantha Chameera rocked Jaffna's top-order with a flurry of wickets that pegged back the scoring rate.
Although Perera fought back with a counterattacking charge, Jaffna's collapse never stopped and their innings was further derailed by a regular loss of wickets.
At 87/7 in the 13th over, the Stallions headed towards certain gloom but Wanindu Hasarange set up a breathtaking boundary assault, feasting on the bowling of Isuru Udana in particular.
Hasaranga smacked five successive fours in the over bowled by Udana and got out in the second last over for a blazing 23-ball 41.
Hasaranga later made an impact with the ball too, capping off a dominant all-round performance but it was not enough to prevent defeat for his team.
