St Elizabeth Technical High School completed the rural area double after an emphatic 62 run win over hosts Manchester High School in the T20 final on Thursday.
Batting first, STETHS rattled up an imposing 162-7. Sean Roye led the way with 37, while captain Malik Williams chipped in with 36 and Odean Binns 31.
In their chase, Manchester High could not cope with the pace of Gavasta Edmond who bagged 3-36 and Kevoni Graham 3-21.
Brian Barnes top scored for the home team with 22, while Demario Hall supported with 20. It meant STETHS added the crown to their Headley Cup and Spalding Cup titles won earlier this season.
Both teams will now turn their attention to the all-island competition which bowls off on Tuesday.
