Saturday night at AAMI Park is exactly the type of Origin-affected game where confidence needs to be kept in check. On paper, Storm vs Roosters is a huge matchup, but the betting picture is messy because both squads have key players coming off Origin duty and late mail will determine a lot. This is not a round where you want to be charging into big positions before final teams are confirmed.
That said, I’ll take Roosters -1.5 as a low confidence play. The market is tight, and rightly so, but I slightly prefer the Roosters if their main Origin players back up well. Melbourne have named Cameron Munster, Harry Grant and Trent Loiero, while the Roosters have James Tedesco named at fullback, Victor Radley among the inclusions and Billy Smith back in the side. The big Storm out is Shawn Blore, while the Roosters are without Daniel Tupou and Fetalaiga Pauga.
Storm vs Roosters Prediction & Tips: 2026 NRL Round 13
Storm Still Fighting for Stability
Melbourne’s season has already had more drama than they would have wanted, but they have at least started to show signs of life after their horror run. The problem is that this is still not the Storm side we are used to trusting blindly. They have had defensive lapses, spine disruption and too many games where momentum has turned against them and stayed there.
Their last start loss to Canterbury summed up the frustration. Melbourne led 18-6 at halftime, but the Bulldogs came over the top to win 30-20. For a Storm team, blowing that kind of position is a concern. It wasn’t just one bad bounce either; Canterbury’s second half pressure exposed a Melbourne side that still looks less stable defensively than usual.
This week, the issue is not only form, but fatigue. Munster and Grant are the heartbeat of this side, and both are involved in Origin. If they back up and play close to their best, Melbourne can absolutely win. If either is managed, limited, or flat, the whole Storm profile changes. That is why final team lists are so important.
At home, Melbourne still deserve respect. AAMI Park is a difficult trip, and Craig Bellamy teams rarely lack effort in these spots. But the Storm are no longer a side where the jersey alone is enough. They need their Origin stars to be close to full capacity, and they need their middle to hold up without Blore.
Roosters Need Their Stars to Back Up
The Roosters had the bye last week, which makes this both helpful and awkward. Helpful because the broader squad has had a chance to freshen up. Awkward because some of their most important players are still coming out of Origin, and that makes the actual strength of the team difficult to assess until late.
Tedesco being named at fullback is obviously a big positive, but the Roosters have already had questions around whether he backs up after Origin. Cody Ramsey has previously put his hand up as a fullback option if Tedesco is rested, which tells you the club has at least had to think through that scenario.
If Tedesco plays, the Roosters look the more reliable side for mine. His yardage, support play and defensive organisation are massive in a game that could be decided by small margins. Sam Walker’s kicking game gives Sydney a strong field position profile, while Radley’s inclusion adds toughness and ball playing through the middle.
The concern is the outside backs. Tupou is out, Pauga is out, and there has been plenty of shuffling around the edges. Against Melbourne, that can be dangerous if Munster gets time and space. But overall, the Roosters feel like the side with the cleaner recent trajectory and slightly more attacking polish.
This is not a bet I’d go heavy on. If late mail goes against the Roosters, I’d be quick to reassess. But as named, I lean Sydney.
Storm vs Roosters Recent History
Storm vs Roosters has been one of the better modern rivalries, with both clubs usually turning these games into high pressure, finals-style contests. Recent meetings have often been tight, physical and decided by execution rather than huge attacking separation. Last season’s clashes again showed how narrow the gap can be when both sides are near full strength, with their round 21 clash ending Storm 34, Roosters 30. The Storm rested plenty in the round 26 matchup, so I don’t take a lot from that game. However, the Storm have dominated the recent history, winning 8 of the past 10.
Recent results:
• 2025 Round 26: Roosters def Storm 40-10
• 2025 Round 21: Storm def Roostesr 34-30
• 2024 Preliminary Final: Storm def Roosters 48-18
• 2024 Round 20: Storm def Roosters 24-8
• 2024 Round 7: Storm def Roosters 18-12
Roosters Slightly Preferred But Keep Stakes Low
This is probably the clearest example on the card of why betting outlay should be smaller this week. If you told me Tedesco, Munster and Grant are all playing close to 80 minutes and all look fresh, this becomes a vastly different handicap than if one or two are late outs or heavily managed.
As of now, I slightly prefer the Roosters. Their bye helps the non-Origin portion of the squad, they have Walker’s kicking game to control territory (if he backs up), and they are a little more trustworthy in attack than Melbourne have been for much of the year. The Storm still has star power, but they have not been the same week-to-week machine.
The -1.5 line keeps it simple. We are basically asking the Roosters to win the game, and at a near pick’em number I’m comfortable siding with the team I think has the slightly better balance. But I want to be clear: this is not a strong bet. This is a smaller play in an uncertain round.
The biggest thing I’ll be watching is final teams. If Tedesco is rested or Munster/Grant are both confirmed to play full minutes, the market could move, and the opinion may soften. If all main Roosters back up, I think Sydney have enough control and edge strike to get the job done.
Low confidence, but Roosters -1.5 is the lean.

Storm vs Roosters Player Prop Bet
It’s been fantastic to see Cody Ramsey get back into the NRL with the Roosters, and he may well get a chance to play fullback this week. If not, he will be out on the wing, where his chances at a try don’t suffer one bit.

Storm vs Roosters Same Game Multi
Leg 1: Roosters (-1.5) – See best bet.
Leg 2 C Ramsey (1+ try) – See above best prop bet.
Leg 3: J Hughes (1+ try) – Whenever Hughes needs to step up and be the main man for the Storm, he inevitably delivers. With Munster and Grant potentially missing, Hughes will be looking to lead from the front.
