Teenager Alice Capsey has scored the joint-fastest fifty in Women's T20 World Cup history as England eased to victory by four wickets against Ireland in Paarl.
The 18-year-old, who was picked up by the Delhi Capitals in the inaugural Women's Premier League auction while in the field for England on Monday, set up her side for victory with 34 balls to spare.
England had bowled Ireland out for just 105, but there were some warning signs for Heather Knight's side as they reached the total with ease, but lost six wickets in the process.
Capsey, who played for Melbourne Stars in the WBBL, was caught by a diving Leah Paul at long-off, to finish with 51 from just 22 deliveries.
England had been cruising towards the win, at 1-70, but lost a number of quick wickets before Katherine Sciver-Brunt hit the winning runs.
Ireland came into the game full of confidence after a shock victory over Australia in the warm-ups ahead of the tournament, but were unable to capitalise on a quick-fire start with the bat.
Gaby Lewis top-scored for Ireland with 36 at the top of the order, but Ireland slid from 2 for 80 to 105 all out. Eight wickets fell to spin, three apiece for Sophie Ecclestone and Sarah Glenn and two for Charlie Dean.
England top Group B with two wins from two matches and ahead of host nation South Africa, who bowled New Zealand out for 67 to win by 65 runs and get back on track after surprisingly losing the tournament opener to Sri Lanka.
South Africa were under pressure after Friday's failure on opening night against the Sri Lankans and the home batting against New Zealand wasn't convincing, posting 6-132 as allrounder Chloe Tryon top-scored with 40.
Left-arm spinner Nonkululeko Mlaba had Kiwi opener Bernadine Bezuidenhout stumped from the second ball of the innings and the home team picked up wickets regularly from there.
Mlaba finished with 3-10 and fellow slow bowler Tryon 2-12 on Paarl's spin-friendly pitch.
New Zealand's 67 came two days after they were bowled out for 76 to lose by 97 runs to defending champions Australia.
