An injury-time equaliser from Matt Sim has given a 10-man Central Coast a deserved point in a 1-1 draw against Newcastle at Hunter Stadium.
Sim scored with a low shot in the 91st minute after the Jets failed to properly clear a long free kick into the box.
Newcastle had gone ahead in the 83rd minute when Serbian striker Milos Trifunovic struck a glancing header in off the far post from a David Carney corner kick.
The equaliser from Sim, who came on the 80th minute for Mitch Austin, capped a brave effort from the Mariners, who are unbeaten in F3 derbies against their A-League rivals since October 2012.
The Mariners lost centre-back Jake McGing to a straight red card in the 24th minute for a lunging challenge on Leonardo which led to the Brazilian being stretchered from the field with a lower leg injury and taking no further part in the game.
Despite the numerical disadvantage, the Mariners regularly caused turnovers and created chances.
Before the send-off, Central Coast were unlucky not to gain a penalty when Mateo Poljak brought down Austin in the 21st minute.
Referee Kris Griffiths-Jones called a free kick on the edge of the box despite replays showing contact was made just inside the penalty area.
The draw lifts Newcastle to 10 points from six games, while the Mariners go to five points.
