2023 SEATTLE MARINERS GRAND SLAM CAMPS



The Seattle Mariners offer summer baseball and softball camps in Washington and Oregon
for baseball and softball players currently in 1st through 6th grade. 
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 Homestead Park the week of July 24-27, 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.)
