Pretoria's young rugby talent has finally won over its harshest critic - Springbok coach Jake White.
White has been critical of the Blue Bulls in the past, but his latest selections have proven Pretoria has what it takes to develop rugby talent, from school level through to the Blue Bulls and the national squad.
Two of the three new Boks from the Blue Bulls Under-21 team - Chiliboy Ralepelle and Pierre Spies - started playing rugby while at school in Pretoria.
The talents of all three were further developed in the Blue Bulls' youth programme.
Tshwane can boast nine Springboks in the current squad of 28, among them captain John Smit and reserve hooker Danie Coetzee who have strong ties with Pretoria.
Two of the four newest caps come from two of the the city's top rugby schools - Pretoria Boys' High and Afrikaanse Hoër Seunskool.
At the next level, the Blue Bulls youth programme has lured some of the best young rugby talent post-matric and turned these players into Springboks.
Ralepelle, an exciting player while at Boys' High, is following in the footsteps of Springbok captain Smit, who also matriculated at the school. Spies went to Affies and joins two other former Affies pupils, Wynand Olivier and Fourie du Preez, in the Bok squad.
The third Bull to get a Springbok call-up, Akona Ndungane, may be from East London, but his rise to prominence is thanks to Blue Bulls coach Heyneke Meyer.
Meyer's system of developing youth has given the Bulls dominance in the national team - much like they have dominated the South African performances in the past four years in the Super 12 and 14 as well as the Currie Cup.
Meyer has turned Loftus Versfeld into something of a Springbok factory, with the Bulls dominating the South Africa Under-19 and Under-21 squads.
Another city school with a proud rugby tradition is Hoërskool Waterkloof, which has more than 10 players in this year's Craven Week squad.
Bok Gary Botha (now released from the team) and Cats captain Wikus van Heerden went to Waterkloof.
Clearly the city's rugby schools are producing results that are the envy of the rest of the country.
But it has not been an easy ride. Meyer arrived in Pretoria when the Blue Bulls were at an all-time low, having ended 10th in the Currie Cup. Since then they have won three Currie Cup titles and reached four finals in the past four years. They won the Vodacom Cup in Meyer's first season and under his guidance they have reached two consecutive Super rugby semifinals.
And apparently White is starting to realise where Boks are bred.
Ralepelle, who is just 19, captained the South Africa Under-21 side at the recent International Rugby Board Under-21 World Championships - at which they lost in the final.
But Meyer believes that the young hooker needs to be nurtured on the road ahead and perhaps has some maturing to do.
Spies was overwhelmed by his selection, dedicating it to his late father, after whom he is named.
"My father was unlucky not to become a Springbok, but he would be proud today," Spies said about the former Northern Transvaal winger who scored 59 tries in 45 matches. "He will be smiling down from heaven today. It's really a pity he wasn't here to see this. He would have loved to be here, and I would have loved it as well."
Ndungane was over the moon when he heard his good news, but did feel sympathy for his twin brother, Odwa, who plays for the Sharks.
"I've worked hard for it and I am overwhelmed at the moment. I've just spoken to my family and they are just as pleased."
Bulls coach Heyneke Meyer said he was delighted that he could produce some more Springboks from his Loftus factory.
"It's a real compliment for us that these guys have been chosen and we're really proud of them.
"I said all along that Pierre would be a Bok before the end of the season and now he is. I'm proud of them."
