Landon Donovan scores hat-trick for the Galaxy but late Blas Pérez goal saved point for Dallas.
A Landon Donovan hat-trick was not enough to get LA Galaxy 3 points in a game that saw FC Dallas break a franchise record scoreless drought of five games.
FC Dallas opened the scoring in the 14th minute from a David Ferreria corner, which was headed back across from the back post by Andrew Jacobson to centre back Matt Hedges, who bundled it in from a yard out.
Donovan equalised in first half stoppage time when Robbie Keane looped a ball over the top of the Dallas defence to allow Donovan to race through on goal, head the ball over Chris Seitz and push in the finish.
Dallas came out of half time with renewed enthusiasm, and Perez put them ahead again from close range after the Brazilian Michel dropped in a free kick near the back post. Subsequent replays showed Perez to be offside when the ball was played, but the officials missed it and the goal stood.
Donovan then hit an equaliser and minutes later another to put Galaxy ahead, driving in a low volley with his left foot in the 73rd minute, and minutes later getting first to a loose ball in the box to steer a shot into the bottom corner for his first hat trick since 2008.
But in the 86th minute Dallas rescued a point from another set piece when Perez, back pedalling, managed to shift his weight and volley the clearing header into the net from the edge of the area.
There was almost a dream finish for Dallas in the 91st minute when Jackson won the ball in midfield before turning and unleashing a 40 yard drive that had the crowd on their feet, only to see it strike the top of the right hand post.
