Duffy (20) has picked up just one wicket in the Volts' twenty20 campaign so far, while conceding 10.77 runs an over, the second-most expensive figures in the competition behind those of team-mate Dirk Nannes.
The Volts are propping up the rest of the competition but have a good chance to break their duck against the winless Stags this afternoon.
Duffy, one of Otago's best bowlers at the death the past two seasons, said it had been a frustrating start to the season for himself and the team after a couple of successful seasons.
''I don't feel too bad. My length stuff isn't going too bad.
''But I'm struggling to find my rhythm at the death. I'm obviously getting tonked a bit and the stats show it.
''I think I'm more trying to place the ball as opposed to just running in and bowling hard.
''I just need to put a few things at the back of my head and not worry about the frustration so much and just let the ball go,'' he said.
With the revamped competition requiring teams to play some games at neutral venues, Duffy is looking forward to finally bending his back at the University Oval this afternoon.
''I'm sick of seeing Seddon Park, after the last four games, to be honest. I'm really keen to play here and hopefully we get a decent crowd in,'' he said.
While Otago has lost all four games to start the season, it was in good positions to win three of them but faltered down the stretch.
Duffy, who conceded 16 runs to Wellington's Jeetan Patel in the last over of Sunday's narrow loss, said it was time for the tide to turn.
''It's been frustrating.
''There have been three games where we have been right in it and should have won, but that's the game of cricket, isn't it? ''Form goes against you and it's quite hard to fight against it.
''They obviously haven't won in a while and neither have we.
''It will be a tight battle. If there is any team to get the ball rolling on, it could be them.''
While coach Dimitri Mascarenhas has named the same 13-man squad for today's game, a few players will be under pressure to perform, with the team's playoff hopes already severely bruised.
Duffy, Otago's second-highest wicket-taker (10) behind James McMillan (12) in last year's campaign, said there was always pressure to perform.
''Probably more so now than ever with the way we have gone in the last few games, but you've just got to embrace it and move on and do what you can with it,'' he said.
