Whitehaven coach Dave Woods is demanding a major improvement after last week’s 46-4 defeat at Doncaster.
Woods said: “I wasn’t happy at all. We looked as though we were resting on our laurels, and that simply wasn’t good enough.”
He added: “We’ve got to work hard this week to right the wrongs. We know we can play better.”
March said: “We did too much defending in the first half.
“We’ve got to be honest. We can still make the play-offs, but we’ve got to play a lot better than we did against Batley.
“We’re all professional and we’ll come back working harder and harder.”
