A record-setting number of 91 teams will compete in the 102nd installment of the Lamar Hunt U.S. Open Cup, which kicks off on April 25th when San Francisco FC squares off against Cal FC in the opening match.

U.S. Soccer announced the pairings for the play-in round, the first round and the second round, which is where USL teams will enter the tournament field. Two play-in matchups will be played on April 25th while the first round is scheduled for May 13th.

In the largest field during the modern era (1995-present), fans will have to wait until round three to see NASL teams enter the fray, and reigning champion Seattle Sounders, who have dominated the U.S. tournament in previous years,  four titles in the previous six years, will enter with every other MLS team in the fourth round.

Here is a closer look at the play-in round, first round and second round pairings:
