Second-tier side Wa Rockets stunned Ghana Premier League leaders Wa All Stars with a 1-0 quarterfinals victory in a local derby on Saturday.
All Stars failed to make their first half dominance count, with Richard Arthur the main culprit in terms of missed chances, when he could have put the game to bed earlier on.
Abdul Ganiyu made a vital challenge in his side's area with Rockets poised to open the scoring, although they were struggling to make much of an impression in the hosts' area. However, after several failed attempts, Benson Akosah pounced on a loose ball and hit the back net, silencing the GPL leaders by the 16th minute.
Two minutes later, Wahida Mumuni sustained an injury following a collision with Rockets midfielder and was replaced by Samuel Atta Mensah.
Back from the break, All Stars gradually found their rhythm and began to push for an equaliser, with Kofi Yeboah narrowly missing the target from a header.
However, Akosah came close to grabbing a brace in a counterattack action on 55th minute but was eventually thwarted.
On 75th minute, Ganiyu flicked on Akoto's long throw near the post, with Arthur shooting wide once more.
All Stars pushed men forward in search of the equaliser but could not find an opening in Rocksters defence, as the visitors held their own to achieve an incredible victory and bragging right against the giants.
