Argentina Women demolished the record for the highest T20 International (T20I) team score with a scarcely believable 427 for 1 – at an average of 21.35 runs per over – against Chile at the Maurice Runnacles Oval (St Albans Club) in Buenos Aires, Argentina, on 13 October 2023. Openers Lucia Taylor (a female record 169 from 84 balls) and Albertina Galan (145 not out from 84 balls) put on 350 for the first wicket (a record stand for any wicket in men’s or women’s T20Is), while medium-pacer Florencia Martinez conceded 52 runs from her only over, including 17 of the 64 no balls bowled by Chile. In reply, the visitors were bundled out for 63 in 15 overs, a sorry scorecard featuring four run-outs, one batter retired hurt and just one innings of any substance (Jessica Miranda’s 27). Seven members of the unranked Chile team were making their T20I debut. Argentina’s 364-run win was the highest margin of victory in any T20I since the format was adopted in 2005.
Bahrain Women made 318 for 1 against Saudi Arabia Women (49 for 8) in Oman on 22 March 2022; Argentina topped this former women’s T20I record by a staggering 109 runs.
Nepal amassed 314 for 3 against Mongolia (41 all out) at the Asian Games in China on 27 September 2023 to take the men’s T20I record from Afghanistan (278 for 3 in 2019) and the Czech Republic (278 for 4, also in 2019).
The three-match series between Argentina and Chile on 13–15 October 2023 resulted in three crushing defeats for the visitors on consecutive days – by 364, 281 and 311 runs, which represent three of the four heaviest defeats by runs in either men’s or women’s T20Is.
Replying to the hosts’ 300+ totals on each occasion, the inexperienced Chileans mustered just 104 runs combined across all three innings. Their bowling fared no better: as of 26 October 2023, five of the six worst-ever T20I bowling performances by runs conceded came in the one-sided series in Buenos Aires, including Constanza Oyarce’s four-over, 92-run nightmare in the first game.
