Stevens beat North East Valley clubmate Sarah Scott 21-13.
Scott initially looked more at home on the green, applying pressure on Stevens and drawing shots with relative ease to hold an 11-6 lead after 13 ends.
But Stevens turned the pressure back on Scott to score four shots on the 14th end and two on the 15th to grab a 12-11 lead.
Scott hauled one back on the 16th but Stevens hit back with another four, when she dragged the jack into the ditch to score a full house with three back bowls adding to the count.
She followed this up with another two shots on the following end to come within three shots of victory.
With the jack then surrounded by six bowls, three from each player, Scott got a one-shot nudge from the umpire’s measure to keep her hopes alive.
But in a display of real class, Stevens made sure of her weight and line, drawing in on the jack with her first two shots of the final end, forcing Scott on the drive.
In an attempt to kill the end with her final bowl to keep her chances alive, Scott’s drive hit its mark, only for it to leave the jack in play out wide with two of Stevens’ bowls remaining in the count.
Stevens then sent her final bowl down, and although falling short, fell within the count for the three she needed for victory.
Both bowlers would have impressed New Zealand selector Mike Kernaghan, who was on hand to witness the contest between two players on the radar for Commonwealth Games selection.
Stevens and Scott form a formidable pairs combination, both locally and nationally, and have had several singles clashes, generally resulting in narrow winning margins.
"We’ve had a few battles but she’s usually got on top", Stevens said.
"It [this win] was due. The last three times it’s been 21-20 [in Scott’s favour]."
"To be fair, she played really well. There were a few holes she just snuck through, and once she got the jack, it was a different story."
Stevens has the distinction this season of having played in all four open centre titles. She was runner-up in the pairs and fours and won her third centre title in the triples just before Christmas.
Sunday’s singles title made it four, and she needs only to pick up a centre champion of champions title in the coming weeks to gain her gold star.
Scott was full of praise for Stevens after the final.
"She played a couple of bombs from which I just didn’t recover. She deserves her win."
This weekend, both Stevens and Scott will be in Auckland with the rest of the 14-strong women’s Commonwealth Games selection squad, after which the squad will be reduced to eight.
A further three will be cut before a team of five will be confirmed for the Commonwealth Games in the coming weeks.
