Castleford dominated the game from the first whistle but Malet Lambert from Hull fought hard to make it a contest.
The Wakefield side began in fine style, rattling up 28 points without reply, full-back Frankie Cowell running in four tries with Aimee Wood crossing for another and Savannah Gaitley adding four conversions.
Just before half-time, Malet Lanbert managed to get their first points on the board when Megan Sage touched down and Katie Russell added the extras to make it 28-6.
The second half proved to be a more competitive affair with Sage crossing again and Russell converting to further reduce the deficit.
The two sides then continued to swap scores with Wood, Shelby Chiunge, Ellie-Mae Smith and Cowell scoring further tries for Castleford with Gaitley adding three conversions.
Sage claimed her hat-trick for Malet Lambert with Russell adding two tries and two conversions but their slow start had left them with too much of a mountain to climb.
However they had the consolation of Katie Russell being named Player of the Match.
