Morton’s effort made him the second highest individual scorer so far this season, bettered only by the Barbadian Ryan Hinds, who had scored 240 against the Leewards in the third round.

The Leewards secured a 77-run first innings lead and CCC reached 44 for one in their second innings when the game was called off as a tame draw.

The match result also confirmed Jamaica as George Headley/Everton Weekes Trophy winners as the Leewards were the only side with a mathematical chance of overtaking them but needed maximum points from all their remaining fixtures to achieve that.

From an overnight 410 for five, the Leewards were able to overhaul the CCC’s first-innings total of 519 by lunch, which they took at 520 for seven.

Morton, who had scored 210 in the Leewards’ victory over Barbados last weekend, collected another double when he swept the off-spinner Ryan Austin for four.

Delivering a timely reminder for regional selectors ahead of the West Indies’ trip to England, Morton brought up his double-century in 401 minutes off 357 balls with 21 fours and two sixes.

Morton was finally out – caught at slip by Floyd Reifer – trying to steer a delivery from Austin to third man, ending his marathon innings.

The 30-year-old Nevisian has not played for West Indies since last year June – against Australia – and while he aspires to return to the top level, he told CMC Sport his current motivation is to play to the best of his ability for the Leewards.

“I would be lying if I told you I did not want to play international cricket but right now my motivation comes from my teammates and doing the best I can for the Leewards,” he said.

Overall, Morton struck 22 fours and four sixes, and faced 403 balls in his historic 450-minute innings.

It was his third triple-figure score this season and he shared in a 94-run sixth-wicket stand with Devon Thomas.

Left-arm spinner Kavesh Kantasingh bowled veteran Wilden Cornwall (5) nearing the lunch break but the Leewards stretched their innings another hour into the post-lunch.

Lower order batsmen Justin Athanaze and Gavin Tonge contributed useful scores that swelled the innings toward 600.

After Thomas scored 39, Athanaze (35) and Tonge (34 not out) scored briskly with a plethora of boundaries.

The Leewards’ total surpassed the previous highest score this season – by any team – of 530 for eight declared by T&T against Guyana in the seventh round at Providence, Guyana.

Left-arm spinner Anderson Sealy picked up four for 170 off 46 overs to be the CCC’s chief wicket-taker, while Kantasingh (3-107) and Austin (3-189) shared the other wickets.

When CCC batted for a second time, medium pacer Tonito Willett (1-19) dislodged first-innings double-century scorer Omar Phillips for 27.

Teenager Kyle Corbin (7) and Nekoli Parris (6) were not out when rain forced the players off the field just before 15:30 h local time.

There was no further play as officials agreed to call off the game.

In the 13th and penultimate round starting Friday, the Leewards will be at home to Trinidad and Tobago and CCC will be back home to face Barbados.
