RUGBY LEAGUE: The Sunshine Coast-based Melbourne Storm under-20s will be looking to arrest a three-game losing streak on Saturday in their round five Holden Cup match against Newcastle.

Five Coast juniors will line up for the side that will play in a curtain raiser to the NRL team at Melbourne's AAMI Park.

The young Storm side started the season well with a 44-24 win over the Dragons at Sunshine Coast Stadium, but have struggled with their defence since, letting in 120 points in their past three games.

"We have been good in patches and only let in six points in the first half against the (ladder leading) Sharks last week (before going down 48-40)," coach Eric Smith said.

"We have got to have the mentality to change the momentum when teams get a roll on."

They might have let some points in but they have no trouble scoring them, putting on 144 points in four games.

"We are the second best attacking team in the competition," Smith said.

"The boys are very confident with the ball in hand."

Coast junior Sam Burns will debut on Saturday beside fellow Coasters and Storm regulars Cory Parker (centre), Nat McGavin (wing), Louis Geraghty (bench) and Lachlan Timm (bench) who will run out for Melbourne on Saturday.

"He's a good young hooker and played for the Falcons colts and his work ethic to training is second to none," Smith said.

"He's worked hard for this opportunity and thoroughly deserves it.

"He's tough."
