Kairo Mitchell struck at the death as Rochdale snatched a 1-1 draw at Tamworth to remain in the hunt for a National League play-off spot.
Sam Waller had kept Tamworth at bay heading into half-time, producing fine saves to deny Dan Creaney twice and Nathan Tshikuna.
But the goalkeeper gifted the Lambs the lead two minutes before the interval, punching Tom Tonks’ corner into his own net.
Tamworth keeper Jas Singh kept out efforts from Leon Ayinde, Aidan Barlow and Ian Henderson, who also had an effort cleared off the line.
But, like counterpart Waller, Singh was at fault as he spilled Kyron Gordon’s low shot into the path of Mitchell and he turned in from close range in added time to leave Dale six points off seventh-placed Altrincham with two games in hand.
