The Wests Tigers kept their slim finals hopes alive with a 26-12 victory over the Sea Eagles, who slipped further out of contention after their fourth straight loss.
Both sides now sit on 24 points and must win their remaining games while relying on other results to advance. After conceding an early try to Tolu Koula, the Tigers responded with 26 unanswered points, led by Adam Doueihi, while Manly failed to capitalise on key chances.
Injuries added to the woes, with Reuben Garrick and Starford To’a both leaving the field with shoulder problems.
