The Mariners offer summer baseball and softball camps throughout the greater Puget Sound area. Mariners Grand Slam Camps provide a unique experience developing skills for all players, whether they are beginners or advanced. Campers are grouped by age and ability and coached by professional educators, former pros and current college players. This allows the instruction and experience to match the level of the campers who attend.
There are three camp sessions to choose from each week:
Ages 7-12 (*6 with experience)
Instruction takes place through traditional demonstration and drills, but mostly via game play where coaches personalize the in-game learning experience. Baseball is a game of situations. Learn the game and love the game!
Ages 9-14 (*8 with experience)
Formalized, advanced instruction. Campers select a defensive position of focus (pitcher, catcher, or infield). All receive batting instruction and practice. Our coaches are experts at teaching. Improve your game. Lots of fun here, too.
Ages 9-12 (*8 with experience)
A discounted price for both sessions, plus additional daily supervised lunch hour no additional cost.
Locations in King, Snohomish, Pierce, Kitsap and Thurston Counties. Plus expansion to the Portland area in Clark County in 2018.
- Campers receive a camp T-shirt, a daily giveaway and much, much more.
- High quality, personal instruction from a talented staff.
- Special Mariners surprises at every camp, including prize drawings and trivia sessions.
- Each camper and their family will be invited to a special clinic at Safeco Field. (date TBD)
- Emphasis on fun!
There simply is no experience like it.
Dates and locations will be available in early January 2018. Check back regularly.
