RED Arrows hopes of winning silverware this 2012 Zambia Rugby Football Union (ZRFU) season were comprehensively blunted after the airmen lost their Knock Out (KO) Cup semi-final match to a Musonda Kaminsa inspired 'Powerhouse' Lusaka side.

Veteran Kaminsa scored five penalties to propel Lusaka to victory and set up an interesting KO final against favourites 'Men At Work' Diggers, who beat Green Buffaloes 10-7 in the other double header semi-final clash played at the Lusaka Rugby Club on Saturday.

The match played under a heavy downpour saw Lusaka taking a 3-0 lead through Kaminsa before Daniel Sakala levelled matters for Arrows with a penalty having missed two earlier on in the match to end the first half 3-all.

Lusaka, who are also the Heroes Sevens champions, went ahead again thanks to Kaminsa who converted a penalty just for Sakala to draw his team level after Kaminsa had failed to score a drop-goal and another penalty.

But it was all Lusaka with Kaminsa adding three more penalties as Arrows ended their season on a disappointing note surrendering the title they won in 2010 when the tournament was last held.

Diggers 10 Buffaloes 3

Earlier, Diggers beat Buffaloes to remain on course of winning their eighth title of the season after beating the Ndola Sevens rugby champions.

The Kitwe side are the 2012 Buildcon ZRFU national rugby league champions, Nchanga 10's winners including the American, Bonnie Mutale, Mufulira, Roan and David Phiri Lusaka Challenge champions.

Kabwe Musonda and Kabwela Mulenga scored a try apiece with Beneya Mukwamba making one conversion while Mulenga failed his but that did not bother Diggers who had Derrick Chewe try disallowed, to marched to the finals as a Sotho Kafwimbe penalty for Buffaloes could do nothing to change the result.
