Eddie Patterson's Glentoran slipped down to fifth place in the Irish Premiership table after being held at home by Ballinamallard United.
The Glens had most of the play but lacked a cutting edge as they aimed to win back-to-back league fixtures for the first time since February.
United, beaten three time by Glentoran last term, did have their chances.
Ryan Campbell had a left-foot shot strike a post while home defender Jason Hill had to make a goal-line clearance.
The Glens pressed late on but a Jordan Hughes shot was too high and Jonathan Addis directed a header over the bar.
Unbeaten Glentoran have five points from their three games played, one more than seventh-placed Ballinamallard.
