TAMPA, Fla. – A league-record 18 USL clubs will participate in the 2017 Lamar Hunt U.S. Open Cup when the tournament kicks off this May with the largest field in its history, as announced by U.S. Soccer on Wednesday. The field also includes a record 21 Premier Development League teams.

The clubs within the world’s largest Division II league will enter the tournament in the Second Round, with Reno 1868 FC set to make its debut alongside some of the Open Cup’s historic names from the USL as it pursues glory in the 104th edition of the legendary tournament.

“As always, we look forward to the competition and opportunity the Lamar Hunt U.S. Open Cup brings to the soccer landscape every year,” said USL President Jake Edwards. “The growth of the tournament’s visibility, in large part because of memorable runs made by USL clubs in the past, have made the Open Cup one of the highlights of the season every year for our teams.”

A total of 56 Open Division clubs, which includes the PDL teams, will begin the tournament in the First Round on May 10. Teams from Division II enter on May 17 in the Second Round. Clubs from Major League Soccer will enter in the Fourth Round, which will be played on June 14.
