Adam Zampa claimed four wickets for 12 runs in four overs as undefeated Australia advanced to the Super Eights of the Twenty20 World Cup, securing their spot with one Group B match remaining after a crushing nine-wicket victory over Namibia in Antigua on Tuesday. Zampa, the leg spinner, continued his stellar performance from the previous weekend's triumph against reigning champions England, contributing to Namibia's dismissal for a mere 72 runs in 17 overs, the lowest total Australia has ever allowed in T20 internationals. In response, David Warner's aggressive 20 off eight balls was followed by Travis Head's 34 off 17, leading the 2021 champions to victory within six overs at Sir Vivian Richards Stadium, dashing Namibia's faint hopes of advancing. Namibia's captain, Gerhard Erasmus, was the top scorer with a resilient 36 before he was caught by Glenn Maxwell off Marcus Stoinis. Zampa's milestone 100th wicket, when he bowled Bernard Scholtz, made him the first Australian male to reach this feat in T20 internationals. "Just doing my job, mate," Zampa, the Player of the Match, commented. "We're pleased, but it's just the beginning of our quest to bring the trophy home, with much more to do." Australia will face Scotland in their final Group B match in St Lucia on Saturday, while Namibia will confront England in Antigua on the same day.
