Diaz was brought back into the lineup by Oscar Pareja after not starting the last four games. He helped find Roland Lamah for two goals and Maxi Urruti for the other.
The Galaxy pressed Dallas early in the match and in the 24th minute had their best chance of the first half on a wide open shot by Romain Alessandrini. The Galaxy Designated Player found himself free outside the penalty box where he ripped a shot on goal that forced FC Dallas keeper Jimmy Maurer to make a diving save.
Minutes later FC Dallas made their first breakthrough as Urruti found the back of the net in the 27th minute. The buildup came off a turnover as Anton Nedyalkov broke up a pass out of the back from the Galaxy. He found Diaz at the top of the penalty box. Diaz made a turn on his defender and found Urruti who dribbled a couple yards before firing off a shot that beat David Bingham at the far post.
Dallas doubled their lead just before halftime as Diaz picked up his second assist on a quick strike from Lamah. Diaz got the ball off another Galaxy turnover in the midfield and then played Lamah who just beat an offside trap before slotting a goal to the far post by Bingham.
LA responded well to begin the second half as Ola Kamara headed home a corner kick from Alessandrini in the 47th minute. Alessandrini’s corner curled into the penalty box where Kamara beat Nedyalkov for the visitor’s first goal.
FC Dallas was forced to play with ten men for the final 20 minutes of the match when Reto Ziegler picked up a second yellow card on a counter attack by the Galaxy.
LA was able to capitalize on the extra space as Emmanuel Boateng and Cole hooked up on the left flank for the Galaxy. Cole beat Reggie Cannon inside the penalty box before laying it off to Boateng.
Dallas was able to keep Zlatan Ibrahimovic quite on the day until the 88th minute on a free kick from 20 yards out. The Swedish international ripped a shot that rattled the far post and out to safety.
It was over when - Mauro Diaz started the game for the first time in four matches. Seriously though, three assists on the day with the last being easily one of his best individual plays to set up Lamah.
Turning point - Could have easily been the red card to Ziegler as it allowed the Galaxy to get more space in the midfield, allowing the Galaxy to get more possession and chances late in the match.
One big positive for FCD - Before the red card, the passing and build up play for Dallas was really good today. Santiago Mosquera was very active, and Lamah worked himself into good spots on the two goals.
What’s next - FC Dallas remains home for another week as they host the Vancouver Whitecaps next Saturday.
