The Mariners offer summer baseball and softball camps in Washington and Oregon. 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 all campers who attend.
Regrettably, due to the COVID-19 crisis, the 2020 season of Mariners Grand Slam Camps has been cancelled.

There are three camp sessions to choose from each week:
- Complete Baseball or Softball Camp (AM half day/4 days) - $150
- Baseball or Softball Skills Camp (PM half day/4 days) - $150
- Baseball or Softball Complete & Skills Camp Bundle (whole day/4 days) - $286

Ages 7-12 (*6 with experience)
(AM half day/4 days) - $150
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)
(PM half day/4 days) - $150
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)
(whole day/4 days) - $286
A discounted price for both sessions, plus additional daily supervised lunch hour at no additional cost.
Locations in Washington's Clark, Franklin, King, Kitsap, Pierce, Snohomish, Spokane, Thurston and Yakima Counties and Oregon's Clackamas, Multnomah and Washington Counties.
