2023 SEATTLE MARINERS
GRAND SLAM CAMPS 



The Seattle 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.

There will be a baseball camp held in Gig Harbor at Sehmel Park the week of July 25-28, and a Softball camp the same week at Heritage Park in Puyallup. (There are other camp locations and dates available, those sessions are the ones located locally.)
