THE Kele Leawere-coached Navosa team showed its intent of claiming a spot in the major division next year after hammering Yasawa 57-23 in the B Division playoffs in Nadi yesterday.
Navosa put on a powerful performance, outscoring their opponents eight tries to three.
Navosa team led 38-10 at the break.
This was Navosa's third win in as many games to top the western zone.
Earlier Navosa had beaten Ba 18-14 and Malolo 16-14.
Leawere said defence was one area they needed to work on.
"It was a good game but we still need to work on some areas," the former Fiji captain said.
"Yasawa scored some tries against us so the defensive pattern needs improvement. It is good to get through to the semi-final.
"I believe the semi-final will be a good game. We will not underestimate the team that will be coming from the Northern Division.
"We want to win the B Division and then the promotion-relegation series and go up to the top flight next year."
Winger Mosese Nawalu scored two tries for Navosa while Ulaiasi Sauvocia, Ratu Vula Senibua, Manasa Tavo, Jone Saurai, Malakai Kuruibua and Timoci Osborne scored one each.
Rusiate Rokotavu kicked five conversions and a penalty. Iowave Kuridawa kicked two conversions.
For Yasawa, the tries came from Epeli Rayagaga, Sailasa Sale, Juita Raiva. Eroni Sau kicked two penalties and a conversion.
Navosa last played in the major division in 2011.
