Johannesburg - South Africa Under-20 rugby coach Dawie Theron made four changes to the starting line-up ahead of the Baby Boks' fifth-position playoff against Fiji at the Junior World Championship in Treviso on Sunday.
Theron retained the same backline from the team that defeated Ireland 57-17 in Padova on Wednesday, but an entire new front row will take on Fiji.
Props Juan Schoeman and Jon Roy Jenkinson will partner hooker Bongi Mbonambi up front.
Flanker Nizaam Carr comes in to the side in place of Francois Kleinhans, who is relegated to the bench, in the only other change to the starting XV.
"Tomorrow's clash is a final opportunity for the guys selected to show what they really are capable of doing," Theron said on Saturday.
"This team has shown plenty of promise and has played some entertaining rugby during parts of the tournament.
"We've scored the second most points in the tournament to date, and also the third most tries of all 12 teams after four matches."
Theron admitted, however, that they had experienced moments when they failed to maintain composure.
"That's why we are playing for fifth tomorrow and not ending off for a higher position," he said.
"In a tournament such as this, the margin for error is small, and I guess we have paid the price for not capitalising on those scoring opportunities in the match against England (in the group stages).
"However, we have Fiji on Sunday and I am hoping that the players make a strong statement.
"It's the last opportunity this group of players will have to play together, so they owe it to themselves to end off with at least a convincing win."
