Chris Chester questioned Wakefield’s resilience after seeing his side crumble at Hull on Friday.
Trinity led 18-10 early in the second half, but the home side roared back scoring 30 unanswered points to claim the victory.
“I felt we had the upper hand until about the 60-minute mark,” said Chester. “We were knocking the sets off well, we were kicking well, I thought we were defending very tough as well but that last twenty minutes I really don’t know what happened.
“We have got to react better to adversity. It swung the momentum. I will question the mental toughness of some of our middles tonight. We gave away a soft try but the very next set we gave a penalty away and they score again. It’s just not good enough.
“They know that and I know that – and we have got to be a lot better. Hull started off really well, they probably caught us hopping a little bit and looked like the side with most energy for the first twenty minutes.
“But we got a foothold in the game. Some smart plays and good kicking and some real tough defence but the last twenty – I think some of the guys waved the white flag a bit too soon.”
