Starting with two games on Thursday night, the competition will ignite on Saturday and Sunday with eight round robin matches leading into the decider at 4pm on Sunday.

Riverside has dominated the shortest format in recent years to make the past four finals, while Launceston broke through for its first T20 title last year.

However, it's league heavyweights Westbury and South Launceston who loom as favourites to reach this year's final after both qualified for 50-over semi-finals in the Greater Northern Cup.

Mowbray will return to the T20 stage after missing last year's tournament, with second-grade outfit George Town electing not to field a side.

Last season: Winner

2018-19 star: Alistair Taylor - 163 runs at 81.50. HS: 101.

One to watch: Ethan Conway. Leads Launceston for boundaries this season and sits fourth in the league's run scorers with three fifties.

Alistair Taylor says: We've had a longish month so T20s are a good way to go out and express yourself. We'll be as full-strength as we can be, have some fun and play some positive cricket.

Last season: Runner-up

2018-19 star: Sam Artis - six wickets at 13.50. BB: 2-18.

One to watch: Peter New. Averaging 30 after moving up to number three and is on track for a career-best season.

Tom Garwood says: We've got quite a young squad but we're excited, there's a fair bit of talent coming through. A few guys will play their first A-grade games which will be good for the club.

Last season: Third

2018-19 star: Sean Harris - 88 runs at 29.33. HS: 44.

One to watch: Nathan Philip. Last season's leading run-scorer hits sixes like they're not even a big deal and struck his first ton of the season on Saturday.

Josh Freestone says: I like [the weekend format], I think it's good that the clubs can have all their players back. It'll be a good atmosphere with all the clubs down here at once and I think it's a good format before Christmas.

Last season: Fourth

2018-19 star: Dan Murfet - 115 runs without dismissal. HS: 82*

One to watch: Kaleb Williams. Has been a regular in the Shamrocks' A-grade side this season after taking 4-21 in round two and should get plenty of game time.

Dan Murfet says: We'll mix the team a up a little bit with a few twos guys that play a bit more in the T20 way, but other than that we're pretty reasonably stocked up.

ELSEWHERE IN SPORT

Last season: N/A

One to watch: Ben Spinks. The Raiders quick is set to wear maroon for the first time this season and will be hungry for wickets.

Luke Scott says: We'll have a pretty young squad again - John LeFevre can only play Saturday. We'll just rotate our young guys through and have a crack.

The cup starts at 5.15pm on Thursday with Westbury hosting Riverside and Mowbray hosting Launceston.
