A blistering 38-ball 78 from Lorcan Tucker wasn't enough for Ireland as South Africa survived a scare to secure a 21-run win in the first T20I at Bristol to go 1-0 up in the two-match series.
Fifties from Reeza Hendricks and Aiden Markram took South Africa to 211-5 in their 20 overs. In the pursuit of the massive chase, Ireland slipped to 84-5 before Tucker and George Dockrell (43 off 28 balls) kept Ireland in the hunt until wickets tumbled at the end of the chase, ending at 190-0 in their 20 overs.
South Africa won the toss and chose to bat first, putting on 23 in the first three overs before Quinton de Kock departed for seven on the first ball of the fourth over. Attempting a quick single, the left-hander was caught short after Harry Tector was quick to move at mid-off and hit the stumps at the non-striker's end.
