Athlone Town made it six draws in a row following a battling display at Derry City.
Derry missed a host of chances, with Michael Duffy the main culprit, and hit the woodwork on three occasions.
Athlone took the lead on ten minutes through Derek Doyle, after Philip Lowry's misplaced pass only found the midfielder inside the box.
Derry equalised on 29 minutes thanks to Rory Patterson's low drive from just inside the box.
Early in the second half a clever pass by Patterson found Duffy, who skipped past a few challenges but his curling effort was saved by Ryan Coulter.
Although Derry continued to push forward, they never really got in behind the Town defence, with Alan Byrne in fine form.
The woodwork came to Town's rescue on 66 minutes when Patterson hit the post, after Coulter had done well to keep out his initial strike.
On 83 minutes, Duffy's 20-yard shot clipped the post, then the same player should have won it.
Derry City - Doherty, Jarvis, McBride, Barry, Timlin; Dooley (Tracey 76), Lowry, Molloy (McNamee 76), Duffy; McEleney, Patterson.
