The nonprofit Puget Sound Senior Baseball League (PSSBL), one of the largest amateur adult baseball leagues in the U.S., will have open tryouts for all baseball players, age 19 and over, during the course of four weekends in March.

Tryouts are at Interlake High School, 16245 NE 24th St., Bellevue, on Sunday, March 10; at Hogan Park at Russell Road in Kent on Sunday, March 17; at Bellevue College, Saturday, March 23; and back at Interlake, Sunday, March 31.

Tryouts are free to attend.

The PSSBL is comprised of 1,100 players forming 72 teams in nine different divisions.

The divisions are organized based on age and skill level, ranging from competitive to recreational. Formed in 1989, this year marks the PSSBL’s 31st season of operation.

For more information including start times and online registration, tryout players and all interested parties are encouraged to view pssbl.com or call 425-644-1901.

Three PSSBL-based teams won national championships last fall. The Puget Sound Reds took the 35 & Over title at the MSBL World Series in Phoenix. The 60 & Over and 70 & Over versions of the Washington Titans won their respective divisions at the Roy Hobbs World Series in Florida.

There are a number of ex-minor leaguers and college players in the PSSBL – even a former Seattle Mariner, but there’s also plenty of room in recreational divisions for players who haven’t picked up a baseball since Little League.

The PSSBL is well known for donating money, materials and labor to youth and school baseball organizations around the Sound as well as other charities. This season it is helping Thomas Jefferson High School, Bellevue College, Northwest Washington Baseball League, and the Wounded Warriors Project.
