Despite Namibia's serious challenge in the chase for 228 runs, South Africa prevailed by 11 runs in a thrilling finish. South Africa reached 228/4 thanks to 101 runs off 53 balls from Lhuan-dre Pretorius and 88 runs off 40 balls from Connor Esterhuizen, the former becoming the youngest T20I centurion among full-member teams (20 years, 161 days). Jan Frylinck's 72 off 36 and Louren Steenkamp's brisk contribution at the top (61 off 44) were the driving forces behind Namibia's response. Namibia appeared capable of their highest T20I chase success for much of the second innings. Before Frylinck's dismissal, Steenkamp and Frylinck put on 119 in 11 overs, giving South Africa a much-needed break. Gerhard Erasmus kept Namibia in the hunt with 30 out of 26, and Ruben Trumpelmann's 21 out of 10 in the final round briefly raised hopes. However, Namibia was held to 217/3 by South Africa. The tri-series winners were also decided by the result, and South Africa will face Zimbabwe on Sunday for the trophy. Namibia made a flying start in the Powerplay, with Frylinck and Steenkamp immediately taking advantage of anything loose. Kwena Maphaka bowled the first over, which went for ten before Frylinck and Steenkamp kept hitting boundaries. In the Powerplay, they combined for eight fours and three sixes, putting Namibia at 67 for 0. As the openers kept the asking rate under control, the assault continued. In spite of South Africa's attempts to introduce spin and vary their pace, Namibia remained ahead of the required rate as Frylinck and Steenkamp reached their century stand in 11 overs. Frylinck got out to Andile Simelane in the 11th over after scoring a fifty off 28 balls and increasing his total of 4s, 6s, and 5s. Erasmus and Steenkamp kept the chase going, with Steenkamp scoring a 37-ball half-century. They added 48, but Steenkamp's injury forced an abrupt end to the partnership. Despite Ruben Trumpelmann's six and four, Namibia fell 12 short of the equation's requirement of 37 off the final two overs for 24. After being asked to bat, South Africa's innings had begun with an equally insistent Powerplay earlier. From the start, Pretorius and Esterhuizen attacked, bringing the score to 45/0 after four overs and 70/0 at the Powerplay's conclusion. In the Powerplay, Esterhuizen was particularly destructive, hitting five sixes while Pretorius added three boundaries. Esterhuizen reached a 26-ball fifty with a six off the first ball of that over, and the acceleration increased despite the field spreading, scoring 24 off Jack Brassell in the eighth over. Esterhuizen added to his boundaries total (8 sixes and 6 fours) before being bowled by Jan Balt. Pretorius then hit a six off Erasmus and a maximum off JJ Smit. Pretorius continued, reaching 70 with a six and four from Max Heingo in the thirteenth over and 80 with a maximum from Balt in the sixteenth. Rubin Hermann made a brisk cameo and supported Pretorius in a 41-run stand, despite Dewald Brevis's brief appearance. Pretorius scored his maiden T20I hundred in the final over by hitting a couple of sixes off Erasmus. This helped South Africa reach a respectable total, but Namibia came so close to surpassing it in a spirited chase.
