First up, Maria Tshiremba's second half brace set up a convincing 29-10 victory over Poland in front of a lively home crowd, before Ayanda Malinga scored a hat-trick in their emphatic 45-0 victory over Czechia.

South Africa then outplayed Argentina 22-0 in their final pool match to remain undefeated in the tournament.

The South Africans were in control for most of the match against Poland and made the most of errors by their opponents, although they will not be completely happy with the hosts' second try at the end of the first half. Despite this mini-slump, Renfred Dazel's team stepped up a gear after the break to add three tries to their two from the first half for a solid win.

The match started with a mistake by Poland from the kick-off, and Malinga didn't need a second invitation to score the first try of the match after only 17 seconds. Three minutes later, following another Polish mistake, Mathrin Simmers went over and with Nadine Roos again adding the conversion, the South Africans were up 14-0.

Poland had their first real opportunity in the fifth minute and they showed great patience on attack, with Oliwia Krysiak going over in the left corner. After the hooter, South Africa missed a lineout throw and a few tackles before Anna Klichowska went over in the same corner to make it 14-10 at the break.

That was Poland's last action on the scoreboard though as Tshiremba scored from the restart, punishing yet another mistake by the home team. After the Polish side were shown a yellow card for a cynical foul, the ball was quickly sent wide to the SA speedster for her second try, which increased their lead to 10 points.

They didn't stop playing when the full-time hooter went and Patience Mokone could celebrate her first try in green and gold on debut for the Bok Women Sevens team.

It was more of the same against Czechia, with Malinga crossing for her first try inside the first minute. Roos and Kemisetso Baloyi also added their names to the score sheet with well-taken tries and with the Bok Women's playmaker converting all three, South Africa led by 21-0 at the break.

They added four more tries in the second half, with Roos continuing to dominate and deservedly scoring her second try, before Malinga and Shiniqwa Lamprecht heaped more misery on their European opponents.

Maria Tshiremba scored two brilliant second-half tries against Poland.

Malinga had the final say as she scored her hat-trick try at the death of a match in which the South Africans not only attacked with vigour and flair, but also defended extremely well to blank the Czechians.

Against the South Americans, Zintle Mpupha scored the opener after three minutes. Argentina had the early possession, but good defence forced them into handling errors, allowing their opponents to get their hands on the ball. Mathrin Simmers ran well and from resulting play, Mpupha stepped inside her defender for the first try of the match.

The South Africans were as guilty as their opponents with regards to handling errors, but ultimately their defence proved the difference in a frantic first half, where no further points were added.

The second half started on a much more positive note for the women in green and gold as Roos ghosted past two defenders to score under the poles. Her conversion was good and the lead 12-0.

Roos then won a crucial turn-over 20m from the Argentinean line and the ball was moved wide where Vianca Boer finished the move with a try in the corner, the first for the former Leopards player in the green and gold.

Roos scored a second, this time after a brillaint blind side break, with the Los Pumitas player lucky to not be carded for a late tackle on the SA playmaker after she hat already dotted down.
