Wests Tigers forward Ava Seumanufagai says that Friday night's win over the South Sydney Rabbitohs proves Jason Taylor's side are far from done in 2015.

Coming into Friday's match against the defending premiers on the back of four consecutive defeats, Seumanufagai played a huge role off the interchange bench in the shock 34-6 win — storming his way for a season-high 17 runs, 162 metres and 22 tackles.

And while his full focus might be on this Friday's clash against the Sea Eagles, the 24-year-old said that having that win under their belts will give the side plenty of belief this week.

"One of our focuses this week has been to have fun," Seumanufagai said.

"I think lately there's been a lot of pressure on us, and it's good to just enjoy being at training.

"The win on Friday really helped — it helps the confidence to have that win.

"We've been working really hard on our defence, so it's good to see some results paying off.

"The boys are really happy with the effort at the moment."
