Afghanistan got back to winning ways at the T20 World Cup as they beat Namibia by 62 runs in what was the final match of Asghar Afghan's career.

The former skipper announced prior to the Group 2 clash in Dubai that he would retire from all forms of cricket following the conclusion of the contest.

Asghar received a guard of honour in his 75th and final T20I before producing a knock of 31 – taking his overall tally to 1,382 runs – as Afghanistan looked to bounce back from Friday's defeat by Pakistan.

Mohammad Shahzad top-scored with 45 – surpassing 2,000 runs in men's T20I – while Hazratullah Zazai hit 33 and captain Mohammad Nabi was 32 not out as Afghanistan set a target of 160-5.

Namibia were aiming to build on their opening win over Scotland, but their quest suffered an early blow when Naveen-ul-Haq (3-26) bowled Craig Williams and Michael van Lingen within the opening three overs.

Hamid Hassan also claimed three wickets as the Eagles' chase fell way short at 98-9.

David Wiese hit 26 for Namibia, but it was not enough to prevent a first defeat in the Super 12s.

History for Shahzad

Dismissed by Pakistan for just eight, Shahzad had another opportunity to reach 2,000 runs in the short format.

This time, he made no mistake with his knock of 45 making him the first Afghan to achieve the feat – and 12th overall.

Naveen shines

It was always going to take a special effort to chase down Afghanistan's total of 160-5, but Naveen quickly put Namibia on the back foot.

The 22-year-old dismissed Williams and Van Lingen within his opening 10 deliveries, and that set his side well on the way to what was eventually a commanding victory.
