The Junior Springboks started their Six Nations Under-20 Summer Series campaign on a winning note after defeating England 30-22 victory in their opening pool match on Friday evening in Verona, Italy.
Playing against a stiff wind, the South Africans went into the halftime break with a 10-7 lead.
As the game progressed, the South Africans grew in confidence as they dominated the scrums and collisions to set up a well-deserved win against a powerful England side.
The Junior Boks started the game strongly when left wing Suleiman Hartzenberg went over in the corner after a brilliant cross kick from Mngomezulu.
But a few minutes later, they were down to 14 men when openside flank Siya Ningza was yellow-carded for a deliberate knock on.
England, playing with a stiff breeze behind them, kicked to the corner and used the maul for lock Ewan Richards to dot down.
The Junior Boks won the next penalty and from a scrum five meters out, No 8 Cameron Hanekom went over, only to see the try ruled out by the TMO.
South Africa ended the first half strong when lively scrumhalf Nico Steyn went over for their second try following a sniping run from right wing Donovan Don to put them 10-7 in front at the break.
With the wind in their backs in the second half, the Junior Boks built on their momentum, with Hanekom scoring his try following some lovely interplay to take the lead to 15-7.
The Junior Boks used their forwards to punch deep holes in the English defence, which led to their fourth try and Hartzenberg's second as they took control at 22-10.
But England replied with an Emaka Ilione converted try to narrow the lead to 22-17, but they then conceded a penalty which Mngomezulu easily slotted to extend the South Africans' lead to eight points at 25-17.
Reserve hooker Tiaan Lange scored their fifth try to take the score out of reach at 30-17, with England scoring a consolation try at the end as the game finished 30-22 in favour of the Junior Boks.
Junior Springbok coach Bafana Nhleko said he was satisfied with the win but was quick to add that they have much work to do for the next two matches, against Ireland on Tuesday and then France.
"We are happy with the win because England are a quality side," said Nhleko.
"They are physical, but we knew what would be coming, however, we pride ourselves on our physicality and our forwards laid the foundation for a good win.
"You could see it was our first match because we looked rusty at times. However, we are happy with the victory, and we do realise there's a lot of work to be done before we play the two teams who finished first and second in the U20 Six Nations this year."
Junior Bok skipper and flyhalf Sacha Mngomezulu impressed with his distribution and decision-making, however, he had an off-day with the boot.
"Playing against the wind in the first half and going into the lead at the break with an advantage gave us a huge lift," said Mngomezulu.
"We will enjoy the win, not get carried away and get straight into preparation for Ireland, who are the Six Nations' top side."
