The Scorpions started the day 118-4 with Paul Palmer Jr joining night watchman Marquino Mindley at the crease.
The pair put on just 13 before Mindley was dismissed by Preston McSween to leave the Scorpions 131-5, just six runs behind the Windwards first innings total of 137.
However, Brandon King joined Palmer Jr in the middle and the two put on an additional 30 runs before Palmer edged to second slip off the bowling of Josh Thomas for 15.
Derval Green came and went for a three-ball duck to leave the Scorpions 161-7 before wicketkeeper/batsman Aldane Thomas joined King in the middle.
The pair added some stability with a partnership of 58 before Thomas went caught at slip off the bowling of Sherman Lewis for 20 to leave the score 219-8 just after the lunch break.
Jamie Merchant and King then mounted a stand of 109 for the ninth wicket, taking the score to 328 when Merchant was dismissed for 58, his maiden first-class half-century.
King also scored his third first-class hundred during the stand and was 119 not out off 154 balls in the end.
The Scorpions eventually got to 346 all out, a commanding first innings lead of 209 runs.
Preston McSween was the pick of the Volcanoes bowlers with 4-96 off 25 overs while Josh Thomas supported well with 3-56 off 21 overs.
Kimani Melius and Devon Smith then began the task of overhauling the Scorpions' total with an opening partnership of 31 before Melius fell to Derval Green for 17.
Captain Kavem Hodge then joined Smith and the pair put on 36 before Smith was next to go, becoming Green’s second victim for a top score of 31.
Alick Athanaze was next to the crease and he and his captain looked comfortable, putting on 34 until the final over of the day which saw Jamie Merchant dismiss Athanaze for 17 to leave the Volcanoes 101-3 off 33.1 overs at stumps, still trailing by 108 runs.
Kavem Hodge is currently 30 not out while Derval Green has taken 2-35 off 10 overs for the Scorpions.
The Warriors won the toss and chose to field first, a decision which looked like the wrong one at the halfway stage of the game.
Former West Indies Under-19 representative Tristan Coleman was in destructive form for the Titans with a rapid 23 off just 10 balls including three sixes.
Cameos from Oshane Walters (20), Wayne Davis (18) and Jamaica Scorpions all-rounder Jamie Merchant (16) helped the Titans post a formidable 106-6 off their 10 overs.
Mikheil Silver (3-11 off two overs) and Andre McCarthy (2-21 off two overs) were the best bowlers for the Warriors.
Cornwall then got contributions from all their batsmen to eventually overhaul the Titans' total on the very last ball of the match reaching 107-4 off 10 overs.
Ockeeno Farquharson (29), Andre McCarthy (23) and Kerry Holness (17) were the main contributors while Jamaica Scorpions batsman Paul Palmer Jr and Captain Damion Ebanks chipped in with 13 and 13 not out, respectively.
Merchant took 2-21 off his two overs for the Titans.
At the close of play, the Scorpions were 302 all-out, after being put in to bat by the Leewards who won the toss. Initially, the decision to field first had looked to be a wise one, as Kirk Mckenzie (3), Jermaine Blackwood (3), and John Campbell (2) were all back in the Pavillion with just 10 runs on the board.
Palmer would, however, stand firm at the crease, and ensure that the Scorpions did not collapse, courtesy of a string of partnerships carefully constructed throughout the innings. The batsman first put on, 44 with Alwyn Williams for the fourth wicket to stop the rot, before featuring in an innings changing 102 with Jamie Merchant for the 7th wicket. Later on, he paired with Nicholson Gordon to add 60 for the 9th wicket and push the Scorpions closer to 300 runs. Paul ended unbeaten with 144 from 233 balls, while Merchant added 55 from 60.
For the Hurricanes, Colin Archibald, Rahkeem Cornwall, Sheeno Berridge took two wickets each.
The Kings posted 102-6 off their 10 overs after the Warriors won the toss and chose to field.
Pacer Andre McCarthy was economical for the Warriors with 1-10 off his two overs.
The Warriors' reply never got out of first gear due to intelligent bowling from the Kings, eventually culminating with them reaching 79-2 after 10 overs.
Openers Ockeeno Farquharson (35) and Paul Palmer Jr (17) top-scored for the Warriors.
Shalome Parnell (1-13 from two overs) and Kenroy Williams (1-20 from two overs) were the wicket-takers for the Kings, which moved back to the top of the table with 13 points and secured a spot in the final with their sixth win in nine matches.
The Warriors are fourth on eight points after their fifth loss in nine matches.
