Pro baseball is returning to the Valley with the newly formed Sonoma Stompers making Arnold Field their home for the 2014 Pacific Association of Professional Baseball Clubs league, which is considered to be between Class A and Class AA of affiliated minor-league baseball.

A non-affiliated six-team June-to-August league, the PAPBC includes Sonoma, the 2012 Pacific Association champion San Rafael Pacifics, the BayCal Lumberjacks, Vallejo Admirals, Na Koa Ikaika of Maui and the Hawaii Stars.

The Sonoma Stompers will be holding their first open tryout from 8 a.m. to 5 p.m. on Saturday, March 1, at Albert Park in San Rafael, with representatives from all the PAPBC teams to be in attendance looking to fill roster spots for the 2014 season.

Conducting the open tryout will be San Rafael Pacifics manager, Dan DiPace, and Stompers player personnel.

Players will be given the opportunity to show off their defensive and offensive skills, and pitchers will display their pitching ability in bullpen sessions and during an afternoon intra-squad game. Invitations to a second tryout, player signings, and spring training invitation announcements will be made immediately following the conclusion of the tryout.

Pre-registration cost is $100 and day-of registration is $150. All players are welcome, however it is recommended that those players wishing to tryout have exhausted amateur eligibility and have previous pro or college experience.

To register, contact Pacifics’ director of operations, Tristan Barbieri, at 415-485-1563, with pre-registration ending at 4 p.m. on Friday, Feb. 28.
