All 16 eligible MLS teams to enter US Open Cup
All 16 eligible Major League Soccer teams will compete in the U.S. Open Cup, which is expanding from 40 to 64 teams this year.
The tournament will start May 15, with the second round May 22 and the MLS teams from the United States entering in the third round May 29, the U.S. Soccer Federation said Wednesday.
MLS had entered eight teams in recent years, with six qualifying automatically and two emerging from play-in rounds.
MLS teams must win five games in the single-elimination tournament to earn the title. The final will be Aug. 7 or 8.
Seattle will attempt to become the first team to win four years in a row.
