Tell me aboutMariners Grand Slam Camps.........
Seattle Mariners Grand Slam Baseball and Softball Camps are real summer camps, like parents remember from their childhood. You can count on top quality and personal instruction while having a blast. After all, it is a game and should be fun - lots of fun! Compare us to other sport camps. You will find that unlike other summer camps; we cater to all-stars AND beginners.  We provide a staff that loves the game, knows the game and loves working with kids. Some camps out there are the other extreme and take things too seriously; they just don't have any fun. We do!

Our balanced approach  ensures a great experience for all, maximizes each camper’s ability to play and perform, and has been working since1993! One of the great things about the game is its culture and emphasis on hustle, sportsmanship, looking sharp, respect, class, history and enthusiasm. The culture of baseball and softball are big themes at our camp reinforced with daily prize drawings, trivia sessions & giveaways. We offer a truly unique experience. We are confident that Mariners Grand Slam Camps are second to none.

We offer Baseball and Fastpitch Softball Camps in King, Pierce, Kitsap, Thurston & Snohomish Counties of Washington State from late June to early August.
