Marange said he was impressed with how his boys adapted to the tough games especially after having to overcome a tough pool during the preliminary stages in Group A which had the ousted champions Rangala Boys, Usenge and Kambare.
"We are champions! We said it before the games that we were going for the title and I am very happy the boys believed in themselves and did it in style.
"To beat the champions twice and claim the top prize was something special and now we shift our gears to the regionals. We celebrate now but the work starts next week," said Marange.
Yala begun the games on the front foot after seeing off Rangala Boys 27-26 in their opening Group A before sealing their spot in the last four after another narrow 31-30 win over Usenge High School.
Their final match of the pool saw Yala pick a 29-17 win over Kambare before humiliating Tuju 43-23 in the semifinals to get to the finals.
