Rabbitohs halfback Adam Reynolds.

South Sydney halfback Adam Reynolds has dismissed praise of his field-goal heroics in Saturday night's 13-12 semi-final win over the Dragons, instead crediting the unsung heroes who provide stiff competition in training for those sorts of moments.

Reynolds was the iceman in the largely frantic sudden-death clash, kicking well throughout and scoring all his side's points and snapping three field goals from as many attempts – two in the final four minutes.

Speaking after the win, Reynolds said there were moments of his game he was happy with, particularly in the closing stages, but there were still moments he'd like to have done better in.

"Without the big boys through the middle laying a platform, Cam Murray coming up with a big play with a one on one [strip], those sort of moments don't happen," he said.

The team did a much better job of winning the key moments than in last week's 29-28 loss in Melbourne.

"We let ourselves down in key moments [last week], we didn't get in range to have a shot [at field goal]," he said.

"I thought that was a really disappointing part about last week. Obviously those games you have to learn from and I thought we learned a lot tonight."

Reynolds devotes countless hours to practicing goals and field goals every week and said it was the scenario-based team set-ups that really paid dividends.

"A lot of credit goes to the coach. Throughout the pre-season and the season we've trained for scenario-based games and being through moments like that at training," he said.

"We have trained for moments like that. All our reserve grade boys, the boys that don't play week in, week out, they do a fantastic job for us, putting us under pressure in those key moments."

He said his troublesome shoulder got through the game OK but would likely require further pain-killing injections for next week's preliminary final against the Roosters.

"Once the needle wears out it will be a bit sore," he said.

"I'm sure [next week] will be no different... I'm not exactly sure what the problem is at the moment.

"Obviously an AC joint there. I've got full faith in the doctors and our medical staff.

"They're worried about our safety as players and I'm sure they wouldn't send us out there if it was something to be worried about."
