Pakistan routed Namibia for 84 in 17.4 overs on Sunday to win their World Cup Group A match by 171 runs.
Wasim Akram took five wickets and Shoaib Akhtar four as Pakistan dismissed the African side for the fourth lowest innings total in World Cup history.
Wasim removed Riaan Walters in the first over, caught by wicketkeeper Rashid Latif for a duck.
Shoaib then struck twice, forcing Stefan Swanepoel to edge to second slip where Inzamam-ul-Haq took a good low catch before shattering Danie Keulder's stumps.
Wasim trapped Gavin Murgatroyd and Louis Burger plumb lbw in successive balls but missed a hat-trick.
Shoaib forced Jan-Berry Burger to edge a simple catch to Younis Khan in the slips and trapped Gerrie Snyman lbw first ball.
Wasim struck again in his next over when he produced another perfect inswinger to win an lbw decision against Melt van Scoor and the World Cup's leading wicket-taker removed Deon Kotze in identical manner.
Namibia's last-wicket pair, Bjorn Kotze and Rudi van Vuuren, then shared a partnership of 42, easily the highest of the innings, before Saqlain Mushtaq dismissed Van Vuuren for 14 in his first over to end the match. Bjorn Kotze finished unbeaten on 24.
Earlier, Yousuf Youhana and Latif shared a run-a-ball fifth-wicket partnership of 58 to help lift Pakistan to 255-9 from 50 overs.
Youhana (43) and Latif (36) came together with Pakistan struggling on 150-4, but they improvised well to increase the run rate. Opener Saleem Elahi top-scored with a patient 63.
