Batley Boys suffered a 28-12 defeat at home to Pennine League Championship leaders Doncaster Toll Bar last Saturday.
The visitors began strongly and opened the scoring with a converted try.

Doncaster hit back to regain the lead as they made good ground to cross for a second converted try which put them 12-6 up at half-time.
Batley put Toll Bar under pressure at the start of the second half with Jayjay Price, on his debut, making impressive yards in attack and was also solid in defence.
Doncaster grabbed a third converted try but Batley responded with good running from Sean Sheard, Aaron James and Rob Garforth leading to a second try of the match for Whitehead, again converted by Dyson.
Batley were back in the game at 18-12 but Doncaster finished strongly and crossed for an unconverted try to give them breathing space.
The visitors maintained the pressure and scored another converted try to seal a 13th straight victory which leaves them 14 points clear of second placed New Earswick Alll Blacks.
Boys man-of-the-match was debutant Price followed by Gavin Davies and Whitehead. Top tackler was Aaron James followed by Davies and Sean Sheard.
