WINDHOEK, Sept 1 (Reuters) - ⁠South African opener Lhuan-dre Pretorius powered his ⁠side to a comfortable 43-run victory ‌over Zimbabwe on Tuesday in the fourth match of the Twenty20 tri-series also involving hosts Namibia.

Pretorius came close to ​a maiden T20 international century, ⁠scoring 94 as South ⁠Africa elected to bat first and scored 185-7 ⁠at ‌the Namibia Cricket Ground.

Zimbabwe were bowled out for 142 in reply with ⁠captain Sikandar Raza top-scoring with 45 and ​pace bowler ‌Duan Jansen taking 3-21.

Pretorius hit 15 boundaries ⁠in his ​51-ball innings before being bowled in the penultimate over. He and Dewald Brevis, who scored 41, ⁠added 86 runs for the ​second-wicket partnership.

Zimbabwe quickly had their backs to the wall, teetering on 66-8 in the 10th over ⁠before the last two partnerships gave their scorecard respectability. They were dismissed after 17.4 overs.

Zimbabwe take on Namibia on Thursday, followed by Namibia ​against South Africa in the ⁠last of the round-robin matches. The two ​teams with the most points ‌after four matches each will ​contest Sunday’s final.
