Keshav Maharaj's three-wicket haul helped South Africa beat Bangladesh by 4 runs at the Nassau County International Cricket Stadium in New York on Monday.
With six needed off last two balls, Mahmudullah was caught near the ropes excellently by Aiden Markram off Keshav Maharaj (3/27), who was South Africa's most successful bowler. The left-arm spinner bowled three full tosses in the final over but the Bangladesh batters were not able to put them away to end at 109 for seven.
Anrich Nortje (2/17) continued to make the most of his form and Kagiso Rabada (2/19) and Marco Jansen (0/17) provided strong support.
South Africa had recovered to post 113 for six after opting to bat on what has proved to be a challenging surface.
