Castleford survived a second-half fightback from Super League strugglers Huddersfield to seal victory.
Denny Solomona put Cas ahead and Jake Webster restored their lead after Jamie Ellis had gone over for Huddersfield.
Luke Gale scored before half-time and although Leroy Cudjoe pegged the Tigers back, Solomona and Webster went over again to put Castleford 30-10 up.
However, Huddersfield rallied and late tries from Giants pair Ryan Brierley and Jake Connor set up a tense finale.

The win was Castleford's eighth Super League victory of the season and moved them up a place to sixth in the table.
Huddersfield's 13th league defeat of the campaign kept them second from bottom after 17 games.
Half-back Gale, who signed a new five-year contract with Castleford earlier in the day, also kicked five goals in the victory and helped to open up the visitors' lead with his first-half try.
The Tigers, who were without on-loan forward Larne Patrick as he could not play against his parent club, were given a scare when Connor crossed with three minutes to play, but they held on to seal victory by an eight-point margin.
