After struggling to bowl out the Bulldogs when their innings resumed at 8-228 courtesy of a quickfire half century from tailender Nick Grant, the Blues were set 292 for victory off 63 overs.

However it wasn't enough as Harper's unbeaten 111 saw the Blues home with five balls to spare.

Captain Jeremy Rowe set a strong platform with his 84 before the 18-year-old ensured South Wagga head into the finals coming off a win under lights at Robertson Oval.

Rowe couldn't have been more impressed with his performance.

"It was a tremendous innings by Blake," Rowe said.

"To score a hundred in any matter is something really special and for Blake that was close to as good an example of two-day batting as you would ever want to see.

"He really got himself in, and we spoke about getting set and not feeling as if we had to go bash and crash from ball one, and he really did get himself set.

"That is part of two-day batting and once he was set I don't think you saw a false shot from him.

"He hit the ball hard, started to hit the ball in gaps and he just has incredible concentration."

It is the second big chase for the Blues in shortened innings after the failed to bowl teams out in 80 overs in the last four rounds.

They scored a two-wicket win over St Michaels in January in similar fashion.

Rowe believes it leaves them in a good place heading into finals.

"It was a terrific chase and one that going into finals is really meaningful," he said.

"Like 290 is a tremendous score no matter where you are doing it and who you are doing it against so full credit to the total that was conjured up but for us to chase it in 63 overs means we've won in a number of different ways.

"We've had wins that have been unique and special in different ways and today was just another one and it is great time to be doing it.

"We can see we may get caught in a similar position in a final and now we've managed to chase down a big total in a small amount of overs we can go in with a lot of confidence that if we are put in that position again them we can get the job done."

However their bowling continues to be a worry.

Despite removing Sam Perry early in the day-night fixture, removing Grant and Charlie Munn (3) proved much harder.

Eventually a run out ended the fightback in the 96^th over.

Grant finished unbeaten on 52 and despite heading into their bowling innings on a high, RSL couldn't find a way to add to their tally in the final match of their season.
