CARSON, Calif. — Chris Seitz made his only save in the 72nd minute and FC Dallas won the first Supporters' Shield in franchise history with a scoreless draw against the Los Angeles Galaxy on Sunday.

FC Dallas (17-8-9, 60 points) had a two-point lead over Colorado coming into the match and held its edge after the Rapids tied the Houston Dynamo 1-1.

The Galaxy (12-6-16) had already locked the No. 3 seed coming into the game and will host Real Salt Lake in a knockout-round game Wednesday or Thursday.

FC Dallas also won the Lamar Hunt US Open Cup in September and advanced to the 2016-17 CONCACAF Champions League quarterfinals on Thursday with a 5-2 win over C.D. Suchitepequez.

FC Dallas in 2016 is the sixth time a team has held two domestic titles going into the MLS Cup playoffs, but none have gone on to win the MLS Cup championship — a domestic treble. It will be more difficult for FC Dallas without their star playmaker Mauro Diaz, who injured his Achilles in a 2-1 loss to Seattle last Sunday.
