Bulldogs coach John Kear has warned his side they must make major improvements from last week’s defeat against Halifax.
Kear said: “We controlled the game for the first 45 or 50 minutes, but you’ve got to play for 80 minutes.
“You’ve got to keep your foot down and keep playing in a constructive, positive manner.”
Batley, who finished fifth in the regular season, were only a point behind Sheffield on the league table.
