LA Galaxy beat LAFC 2-1 at Dignity Health Sports Park on Saturday to endure a second-half win over Altraphico.
Both goals appeared to be on the way to a comfortable victory over the Galaxy in the opening half hour, but the result could have cast doubt on the performance of the whole result in the wrong end of three goals that were not allowed by LAFC.
Carlos Vela was sent off twice in the 79th minute by Cristian Arango for a foul on Latif Blessing twice.
Samuel Grandsir provided two assists for the Galaxy and in the 13th minute Javier Hernandez, who cleverly slipped off Mamadou Fall's shoulder, made his first decision for the Galaxy with his first cross.
The second second from Sega Coulibaly proved to be enough as the Galaxy moved on to win four and lose one of their opening MLS games this season.
The victory gave LAFC a point in the Western Conference, a 2-2 draw with Toronto and a second-place finish with Real Salad, who could not move to the top.
With a 1-0 win over the Columbus Crew, the Philadelphia Union topped the Eastern Conference.
In the second minute, the Union team took the lead in a bad situation, but the team goalkeeper Eloy Room mistakenly kicked the ball into the box and took the lead before the ball went into the goal.
Jim Curtin was pleased that the crew was trying to break down the rest of the game and could not create anything.
Orlando City moved to Orlando City in the Middle East with a 1-0 win over the Chicago Fire, who lost 2-1 at home to Montreal.
In other early games on the East Coast, Leonardo Kamnan scored a hat-trick to give Inter Miami a 3-2 victory over the New England Revolution, their first victory against Inter Miami.
In late Saturday games, Nashville beat Sporting KC 2-1 and Houston Dynamo beat Houston Dynamo 4-3 in the San Jose Earthquakes 4-3.
