Glentoran and Linfield took a point apiece from the first derby game of the season between the big Belfast rivals.
Andy Waterworth put the Glens in front on seven minutes when he stole in ahead of the Blues' defence to meet Jim O'Hanlon's cross and fire home.
Billy Joe Burns levelled when he thumped a left-foot shot into the top corner of the net after an hour.
Both sides had late chances to win the game but Jay Magee and Ryan Henderson saw headers fly narrowly wide.
The Glens, who beat David Jeffrey's side in all four league matches between the sides last season, suffered a setback before the game when captain Colin Nixon failed a fitness test on a knee injury.
The Blues' teamsheet included veteran defender William Murphy, who was making his 600th appearance for the league champions.
The game got off to a flying start when Waterworth nipped in front of defender Albert Watson to poke the ball home from four yards out.
Linfield had chances to equalise but Brian McCaul saw his drive palmed away by Elliott Morris and Robert Garrett was tackled by Marcus Kane as he ran through on goal.
The lively O'Hanlon fired a left-foot shot wide of the post before half-time.
The home side began the second half brightly and Jimmy Callacher forced a save from Alan Blayney, while Waterworth fired a shot over the bar.
Burns drew Linfield level on the hour when he made space for himself and unleashed a left-foot piledriver into the top corner after the Glens had conceded possession.
Burns could have added a second but his shot across the face of goal whistled wide of the post.
Niall Quinn also went close to giving the visitors the three points when his free-kick was saved by Morris.
Late in the game, Magee's header from a corner flew over the bar and then substitute Henderson watched his headed effort go inches wide in added time.
