Round 19 Preview — 2026 NRL SeasonNRL Analytics

Wests Tigers v Warriors

Koroisau out — Lanyon debuts at hooker. Squad ±/G gap of 14.0, the widest of the round. Strong tip: Warriors by 12.

SavvyPlays · 10 July 2026 · Campbelltown Sports Stadium, Sydney · Friday 10 July · 8:00PM AEST

The Tigers lose Api Koroisau this week — their most important player and the organising heart of their attack, a Disruption Score of 3.8. Josese Lanyon, with no recorded NRL minutes, takes the No. 9 jersey. It comes at the worst possible time: the Tigers' full named squad averages -9.0 ±/G against the Warriors' +5.0 — a 14.0-point per-game gap, the widest squad-quality gap of the round.

The Warriors are 4-1 over the last five head-to-head, though the Tigers took the most recent meeting 32-14 in Auckland in R4 this season. Campbelltown is no fortress — the Tigers win just 41% there — and the CI/DS edge runs 2.7 to the visitors. Even at 71% Best 17, still missing Watene-Zelezniak, Tuivasa-Sheck, Barnett and Capewell, the Warriors' depth is too strong. Strong tip: Warriors by 12.

SavvyPlays Tip — Strong

01Warriors by 12

Three signals combine for a Strong tip on the Warriors. First, the squad-quality gap: Warriors +5.0 ±/G across their named squad against the Tigers' -9.0 — a 14.0-point per-game spread, the widest of any R19 matchup. The model agrees, putting the margin at -12.1 against the home side.

Second, the Koroisau blow. The Tigers' hooker is their best player and his absence (DS 3.8) is amplified by the replacement: Josese Lanyon has no recorded NRL minutes. Third, the venue is no shield — the Tigers win just 41% of their games at Campbelltown, and the CI/DS edge of 2.7 sits with the visitors. The Warriors are 4-1 over the last five meetings. Strong call: Warriors by 12.

Venue & Head-to-Head

02Venue & Head-to-Head

Campbelltown Sports Stadium gives the Tigers no real edge — they win just 41% of their matches there, one of the weakest home-venue records of any side in this round.

The Warriors hold a 4-1 edge over the last five meetings, but the one Tigers win is the most recent: a 32-14 away victory in Auckland in R4 this season. Before that the Warriors had won four straight — 34-14 (2025 R19), 26-24 (2025 R4), 28-16 (2024 R21) and 30-22 (2023 R24). The R4 result came with Koroisau on the field; this week the Tigers must try to repeat it without him.

Match Analysis

05Key Matchups & Narratives

The hooker mismatch defines the game. Api Koroisau out for a debutant-level replacement in Josese Lanyon, while the Warriors field Wayde Egan at +10.3 ±/G. Ruck speed and middle service should run one way all night.

The Warriors' spine is humming. Chanel Harris-Tavita (+11.7) and Taine Tuaupiki (+10.7) are both in career-best form, and Ali Leiataua (+14.9) is the best centre number named in this fixture. Maire Martin at halfback is the one unknown — no recorded NRL minutes — but he is surrounded by positives.

The Tigers' problems run deeper than the hooker. Jarome Luai (-10.5) and Terrell May (-15.1) carry two of the worst ±/G figures of any starters in the round. Adam Doueihi (+5.6) and Samuela Fainu (+7.2) are the only genuine positive levers in the 13.

The counter-case: the Tigers won the most recent meeting 32-14 in Auckland this season, and the Warriors are still missing four of their Best 17. But that R4 win was built on a Koroisau-led ruck attack the Tigers cannot field this week.

Koroisau Out — Lanyon Debuts

A Disruption Score of 3.8 understates the football impact. Koroisau is the Tigers' best player and their entire middle-third attack routes through him. His replacement has no recorded NRL minutes, against a Warriors side whose hooker is running at +10.3 ±/G.
