Polenta’s header gives Galaxy 2-1 win over Dynamo
Los Angeles (6-1-0) and Houston (4-1-1) each entered with a four-game winning streak.
The first two goals came on penalty kicks. Los Angeles striker Zlatan Ibrahimovic converted in the 31st minute, and Houston midfielder Alberth Elis scored in the 53rd. Ibrahimovic was pulled down at the far post and sent the penalty kick off the hands of David Bingham for his seventh goal of the season and sixth in his last four games.
Elis, who was tripped at the edge of the 18-yard box, rolled his penalty just past the diving David Bingham for his fourth straight game with a goal.
Houston eliminated the Galaxy from the playoff contention last season on the final day of the regular season.
