The 15-man squad made the journey from Wewak to the Western Highlands Province arriving on Thursday morning.
Led by player/coach, Alex Kilus, Mantas got straight down to business winning their first two games on Thursday against Rovers and Pirates.
"We came here to play and show the rest of the country that we can play softball," said Kilus.
Wewak which is one of the smallest softball associations in the country has four men's and four women's teams that play in the competition back at home.
