The Warriors have clocked up their fifth defeat in a row after losing 26-10 to the Newcastle Knights, who sit bottom in the NRL.
After starring in last week's win over St George Illawarra, five-eighth Brock Lamb was again outstanding, setting up Mitch Barnett's opener before putting Lachlan Fitzgibbon through a hole in the 60th minute for what proved to be the match- winner.
Lamb was rewarded with a late try on top of his two try-assists.
It is the the first time the Knights have posted consecutive wins since rounds 23-24 in 2015 however they remain last on the ladder.
The Warriors scored a consolation try through rookie Nathaniel Roache, however pressure is beginning to mount on coach Stephen Kearney after his side's fifth straight loss.
Lamb put Barnett through a hole close to the line to open the scoring in the seventh minute.
And the Knights' back-rower had his double just four minutes later after exploiting some lazy Warriors goalline and ruck defence which summed up the visitors' day.
After the Warriors pegged back the score through David Fusitua, the Knights had several chances to extend their lead but twice elected to take the two points as they went into the break up 16-4.
