Castleford assistant coach Ryan Sheridan says the team remain confident of making the top five come the end of the season.
The Tigers fell short to a 4-0 defeat at St Helens on Friday night.
Castleford are currently sixth in the Super League table, two points behind Hull FC, Wigan, Salford and Warrington, who are all joint in second.
Daryl Powell’s side face Hull FC [home] and Wigan [away] in their final two games of the season.
Sheridan said: “It is in our hands so what will be, will be. We are still in the mix and that’s the main thing.
“We are still in the fight. We are still in with a shout so we will review the game and move onto a massive game next week for us.
“St Helens was an opportunity missed so we will learn the lessons from it. We’ve two games left and we’ve got a tough one next week. Hull were beaten tonight so we will move into next week and then we head over to Wigan.
“We are developing a lot as a team and our characteristics are growing as a team so there are some positives to take.”
