The 1999 Major League Soccer season was the fourth season of Major League Soccer. It was also the 87th season of FIFA-sanctioned soccer in the United States, and the 21st with a national first-division league. This was the last season which used the 35 yard line shootout rule to resolve tied games, and that of the countdown timer, with MLS Cup 1999 adopting the IFAB-standard running clock thereafter.
The regular season began on March 20, and concluded on October 10. The 1999 MLS Cup Playoffs began on October 16, and concluded with MLS Cup 1999 on November 21. D.C. United won their second double by winning the Supporters' Shield and defeating the Los Angeles Galaxy in MLS Cup.
Overview
Season format
The season began on March 20 and concluded with MLS Cup on November 21. The 12 teams were split evenly into two conferences. Each team played 32 games that were evenly divided between home and away. Each team played every other team in their conference four times, for a total of 20 games. The remaining schedule consisted of two games against each team from the opposite conference.
The top four teams from each conference qualified for the MLS Cup Playoffs. The conference semifinals and finals were played as a best-of-three series, and the winners advanced to MLS Cup. In all rounds, draws were broken by penalty shootout if necessary. The away goals rule was not used in any round.
