Thirty-three players have been called up for the Cricket Tasmania Premier League's newest entity in its maiden season, 15 of whom have played two games or less. 

South opener Sean Harris received a late call-up last weekend and blasted 173 not out - the highest ever score by a Raider - to inflict a shock defeat on T20 premier North Hobart.

This weekend the right-hander is back playing for the Knights in a grand final rematch against Westbury. 

"I think it was always a one week thing - I wouldn’t have blamed the Raiders if they wanted him again but they were pretty open to letting him come back," Waller said.

"It’s good that the partnership’s working that’s for sure, there’s a mutual benefit for both parties.

"They’ve been good with that and I think if it’s to work that’s how it got to be, so I’ve got only positives from my end on the partnership.

"It was a hell of a knock and to have him back after that, he’s made some runs against some first class bowlers so it's a real big plus for us."

Westbury will lose Jono Chapman (unavailable) and three others to the Raiders this week, with Jared Mason, Conrad Chugg and Liam Ryan filling the void. 

Shamrocks skipper Richard Howe said bowling line and length would be key against a batting line-up boasting Nathan Philip, who averages more than 103.67 after nine innings.

"It could determine the layout of the top three," Howe said of the match.

"We just have to work as a bowling group to make sure we’re not going to let Nathan free his hands and get on top.

"But at the same time there’s four or five other guys there who are very capable of a big score so we’re definitely not wholly and solely focused on one person."

MOWBRAY will need to overpower a rampant Launceston side to avoid a second wooden spoon.

The Eagles should regain under-15 state player Spencer Hayes for their season finale, while BBL debutant Jarrod Freeman could come in for one or two weeks.

Bowling all-rounder James Storay, who has been one of the shining lights for John LeFevre's side this season, will miss the second week to get married.  

"It’s a good opportunity for us to finish on a positive and really look towards next season in a couple of things we might like to do with the side," LeFevre said.

"We’re aware that we can have a bit of an effect on how the finals play out at this stage and a win might be able to elevate us to a higher ladder position.

"We’re a pretty proud club so we certainly don’t want to finish bottom of the ladder and playing good cricket the next two weekends is how we go about avoiding that."

Launceston comes fresh from a thumping Statewide T20 win over Longford, where Tom Gray starred with the incredible figures of 5-2.

Captain-coach Alistair Taylor, who is likely to keep for the top-placed Lions, said his form paceman would be handy come finals.

"It was really impressive to beat a really strong team like that," Taylor said. 

"[Tom's] been fantastic, he’s starting to get some good rewards when he comes back to playing to Launceston from the Raiders.

"He’s learned heaps form the Raiders concept, so it’s only improved his cricket which is fantastic for Launceston in the long run."
