In an inglorious end to the home and away series, Southcity thrashed Tumbarumba 52-18 to land the coveted number one ranking for the Group Nine finals starting next weekend.

The Bulls scored nine tries to three to rout the Greens, but Southcity captain-coach Daniel Fitzhenry was later hardly doing cartwheels with excitement.

Clearly disappointed by the spoiling tactics employed by Tumbarumba, Fitzhenry was just pleased to get the game Greens out of the way.

"It was a frustrating game," Fitzhenry said later.

"The blokes (spectators) deserve their money back."

Taking stock of the situation, Fitzhenry's disdain was so easy to understand after Tumbarumba virtually brought the contest to its knees.

Finishing on a low, the Greens were on their worst behaviour on Saturday as they trotted out niggling and, sometimes, unsavoury antics.

Rookie referee Sean Skeers was caught in the middle of it all and had trouble coping.

Amid the myriad mistakes from players and officials, Fitzhenry could definitely take consolation from Southcity's remarkable charge to top spot on the Group Nine table.

Reflecting on a landslide victory that guarantees Southcity a major semi--final at Harris Park in a fortnight, Fitzhenry admitted the Bulls season had not always been completely on course.

"After we dropped the first two games I wasn't thinking about the minor premiership," he said.

"It's all right to say mission accomplished now, but it's been a long time in the making."

For Fitzhenry, the circumstances might not have been ideal on Saturday, but the result was certainly perfect.

"We got there in the end," he said..

"We're got no injuries, and not we've got a week off.

"We'll be rested and ready for whoever we've got to play (in the major semi-final)."

From the start, Southcity treated Tumbarumba with football contempt on Saturday.

The Bulls were roaring with a 16-0 lead inside 13 minutes and had stretched the advantage to 22-0 after Fitzhenry scored a magic solo try in the 20th minute.

By the time Nick Skinner pounded his way over off a dream pass from Pani Manawatu, Southcity was up 28-6 and headed to half-time.

It was just more of the same in the second half, with Nathan Rose showing up the Greens to score a softish try in the 45th minute.

As much as Tumbarumba pegged a couple of tries in the second half, the Bulls were bolting.

Fitzhenry had a hand tries to Rose in the 54th minute and 74th minutes to cap a fabulous personal performance.

Likewise, Rose finished with three tries and rivaled Fitzhenry as the best back, but forwards Tim Hurst, Jordan Shepherd and Nick Skinner were also outstanding.

The Bulls pack lacks weight and size, but more than makes up for it in skill, speed and utter determination.

Fitzhenry said later Southcity had shown "glimpses" of premiership quality.

The same could not be said for Tumbarumba.

Yet again, the Greens relied on the individual flair of Fijians Kitione Rasotale and Iliesa Takubu and company rather than on marvellous team-work.

The off-season has come at the right time for Tumbarumba.
