Debutante Lizelle Lee with the bat and Sunette Loubser with the ball laid the foundations for South Africa Women to beat Bangladesh Women by six wickets in the first One-Day International in Benoni.
Leg-spinner Loubser took three wickets to restrict Bangladesh to 149 for eight before Lee's 77 helped the Proteas reach their target in the 38th over.
Following a 3-0 series win in the Twenty20 Internationals, this was another dominant performance from the home side.
Loubser led the side with the ball to finish with a haul of three for 28 on a slow wicket, her wickets coming late in the innings to peg Bangladesh back.
For the tourists, opener Fargana Hoque top scored with 63 and gave her team-mates a solid base to bat around but once she was out in the 37th over, South Africa took control.
Bangladesh added just 32 runs in the remaining 13 overs as Loubser and her team-mates took charge.
Lee and Trisha Chetty (39) then put on 80 for the first wicket to break the back of the run chase but as Bangladesh fought hard, it needed a mature performance from Lee to finish off the job.
"I'm really proud of the way Lizelle batted today," captain Mignon du Preez said. "It was quite difficult batting upfront and she and Trisha set us up for the target with a good opening partnership.
"She structured her innings really well and adapted with ease to the conditions. The rest of the batters in the order also chipped in."
The second game in the three-match series is on Sunday (22nd September) in Johannesburg.
