WINDHOEK, July 23 - Zambia booked a place in the semi-finals of the Cosafa Castle Cup with a 2-0 win over the Seychelles in the Group C mini-tournament on Sunday.

First half goals from James Chamanga and Ignatius Lwipa secured the win over the islanders, who had secured a surprise victory over hosts Namibia on Saturday.

Zambia, twice winners of the annual southern African championship, will host Botswana in the semi-final next month while defending champions Zimbabwe are up against World Cup finalists Angola in Harare in September.

Zambia dominated their island opponents and opened the scoring in the 33rd minute through Chamanga, who tapped-in a square pass from Dube Phiri.

A second goal was added by Lwipa, latching on to a pass from deep in defence and lobbying over the head of Seychelles goalkeeper Nelson Sopha in the 44th minute.

Zambia also hit the woodwork through Rainford Kalaba, who also had a close-in header late in the game ruled offside.

Hosts Namibia came from behind to beat Malawi 3-2 in the third place playoff match earlier in the day.

Playing under new coach Ben Bamfuchile, Namibia went behind to a 19th minute goal from Moses Chavula but Heinrich Isaaks equalised on the stroke of halftime.

Namibia scored a minute after the break with a debut goal for Rudi Bester and then extended their lead with a penalty from Henrico Botes after Maupo Msowoya had handled on the goal line. The Malawi defender was sent off for the offence.

A free kick from James Chilapondwa reduced the arrears in the last five minutes.
