THE Knights picked up their first win of the Championship season with another performance of mixed fortune against Moseley at Castle Park.
Unlike the defeat at Cornish Pirates last week, Doncaster produced a superb first half show but found themselves under pressure after the break only to hold out well for the much-needed victory.
Tom Luke put the Knights ahead after six minutes with a penalty before converting after David Bradford crashed over for the first try following a fine pass from David McIlwaine.
The second try came on 19 minutes when a brilliant Knights maul had Moseley in complete disarray allowing McIlwaine in to score.
Doncaster produced a superb period of defensive work, forcing Moseley back with fantastic tackling after a spell camped on the five metre line.
The industry was rewarded further on 37 minutes when Dougie Flockhart collected his own kick, passed to Bradford who made great ground and laid off to Michael Keating to touch down, converted by Luke.
It was somewhat unfortunate that Doncaster conceded before the break but Moseley put themselves into the contest through a fine solo try from Ben Pons who dodged several tackles and found a gap to score, converted by Bradley Davies.
Those were seven points that seemed to give Moseley heart for the start of the second half as the emerged strong, piling on pressure for the opening 15 minutes.
But it was the Knights who grabbed what would prove to be a vital try against the run of play.
Ollie Goss reacted superbly to intercept a pass and race three quarters of the pitch to score under the posts, Luke converting.
Moseley hit back immediately as PJ Gidlow failed to make a confident claim of the kick allowing Michael Maltman in to steal and dodge two tackles to score, Davies converting.
Moseley continued to force the issue but the defensive work from Doncaster proved enough to keep them at bay for almost the entire remaining time.
The visitors did grab the final try of the match in injury time when good ball work put in Andrew Reay to score, conversion by Oliver Thomas.
It was a victory that brought relief for the Knights but they may have been disappointed the scoreline was not wider.
