A combination of sheer madness from Amavubi goalkeeper Jean Claude Ndoli and poor finishing from the strikers helped Tanzania to a 2-0 victory in the first of two quarter-final matches played yesterday at Lugogo Stadium, Kampala, Uganda.
Victory looked on the cards as the Taifa Stars dominated a poor wasps' team in the first half, taking the lead through a fine Amri Kiemba volley on the 33rd minute.
After the break, Milutin 'Micho' Sredojovic went for a more offensive approach by bringing on two strikers in Bernabe Mubumbyi and Imran Nshimiyimana and the move looked like it would pay off as Rwanda took the game to their opponents.
But just when the 1999 champions looked like they would get some reward for their pressure, Ndoli failed to hold onto a low shot by Tanzania's midfielder Mwinyi Kazimoto only for Bocco to double Tanzania's lead just eight minutes into the second half.
Amavubi's woes were further compounded when center-back Ismail Nshutiyamagara had to be replaced by Fabrice Twagizimana after a nasty shoulder injury.
Rwanda's skipper Haruna Niyonzima, who struggled to exert his authority on the game in the first half, found his rhythm after the break but his crosses could not be converted.
Tanzania, who won the competition in 2010, are chasing for their fourth title.
In the other quarter-final, Zanzibar needed penalty shootouts to see off Burundi.
