West Riding Challenge Cup holders Rimington moved into the second round with a 2-1 win at Huddersfield Amateurs.
Rimmy started brightly and had early claims for a penalty, Dinsdale heading to Benfield, whose goalbound header appeared to be blocked by a hand.
And on eight minutes a Rimington move broke down and the hosts countered to maximium effect, the centre forward breaking away and shooting past Kershaw.
The home side were then unlucky to see a chip just loop over the bar.
On 15, McLean was sent through but his effort was well blocked by the keeper, and this was the forward’s last involvement as he pulled up with an injury, to be replaced by Hickling.
Dinsdale then flicked a header into the path of Baygot, but the keeper saved with his feet and he was at it again keeping out a Dinsdale header before half-time.
In the second half, the visitors stepped up their game, and full back Rawcliffe went on a marauding run down the left only to see the keeper tip his strike round a post.
A free-kick by Hickling was headed down by Dinsdale to Benfield, and even though his first effort was blocked he showed great poise in chipping the ball over everyone and just under the bar for the equaliser.
The visitors then went in front as Walsh found Dinsdale, who sent the ball to Baygot to ram home a volley.
Rim were now rampant, with chances being created but not taken, but the holders did enough to advance,
Manager Terry Braithwaite said: “This is a great result coming away in the first round against a decent side.
“We would love to repeat last season’s epic run but we will need everyone to start firing on all cylinders. Something is missing at the moment and we need to find it soon or it will be too late.”
