Its record of patchy performances within games in a season that has so far only delivered one win is something Tasmania's franchise will be looking to turn around in today's clash against the struggling Sydney Thunder at Bellerive Oval, says leg- spinner Cam Boyce.

"We know what we've done wrong, and we've addressed that, and we know if we can click with both bat and ball I believe we can do some damage in this competition," Boyce said of the side which went down to the Scorchers by six runs on Tuesday.

"We've been on and off with both bat and ball, and it seems like we're doing just the one thing really well, we know if we can do both things (bat and bowl) well we know we can come away with the right result."

The 24-year-old Queenslander, who was a member of the Bulls team which defeated Tasmania in the 2011-12 Sheffield Shield Final, played six games and took six wickets (at 20.16) for the Adelaide Strikers last season.

After being 12th man for Hobart's four outings, he is likely to get his first run in the purple today with Xavier Doherty on Australian duties.

"I bowled well down here last year (when he took 3-17) and did well for Australia A as well (against the England Lions) so I think this wicket suits me," he said.

"Dohey has been really good for me, and I've been talking to him a fair bit for me, and it would have been nice to bowl with him.

"He has said to me to make sure I attack the stumps and have fun, so I will be going out there all guns blazing and looking to take poles.

"The way the batters bat now, you have to be as positive and aggressive as you can be."

Bowling all-rounder Joe Mennie has been added to Hobart's squad, who sit second last on the table and need a win to stay in touch with the top four.

The Thunder have lost their past 18 games, but have the talents of Mike Hussey, Dirk Nannes, Gurinder Sandhu and Ajantha Mendis at their disposal.
