What should a camper wear to camp?
We ask that the campers dress for camp as they would for practice. Some examples include: tee shirt/sweatshirt, baseball pants or sweats, athletic shoes or cleats (no sandals/flip flops), athletic cup, team uniform or practice gear are also worn by many campers. If the weather is very hot some campers will wear shorts on those days. Make sure to bring a jacket for cool or rainy days. Please have campers name marked on all valuable items.

Do you have an Inclement Weather Policy?
Regardless of weather, camp will never be canceled, even if we encounter rain. We have rain-specific activities that continue to enhance the learning and fun. Rainy days happen here in the Northwest, but are typically light and pleasant. Let's play ball!

What should each camper bring with them to camp?

Make sure camper's name is clearly marked on all gear!

All campers please bring snack and plenty to drink (we break for snacks at 11:00 in the AM and 2:00 in the PM)

Bring lunch if you are attending the Complete Extended-Day Camp or Complete & Skills Camp Bundle.

For Catchers camp we do have gear but you may bring your own if you like.

Any other ball gear of your own you would like to use like helmets, etc.

My daughter loves baseball, does she have to attend the softball camp?
She may choose either the baseball or softball camp. Both are great. UW Husky pitching coach, Lance Glasoe, designed the curriculum for our softball camp. Your daughter will receive excellent instruction in a high energy, fun, instructional atmosphere. If she can't attend a softball camp, many girls have attended our baseball camps and loved it! The base skills are the same except for pitching and slap hitting. Given our camps are coordinated by certified teachers, you can be assured that your daughter will feel comfortable and have a great time. Some girls have signed up with a friend to make them feel more at ease.

Can I reserve a spot via phone or email?
No. All openings are secured on a first come, first served basis. A completed application and full payment must be received via our online checkout.

How do we get signed up?
Simple. Just go to www.mariners.com/camps and select the "Register Now" button.

What kind of staff do you assemble?
Each camp location is lead by at least one certified teacher - and typically more - to ensure safety, fair play, and proper structure. Most of our coaches have played college baseball or coached at the high school level. All our staff are trained in how to properly work with player in the 6-12 age range.

My child wants to attend both the Complete and Baseball Skills camp. Is this OK?
Yes. In fact, this is quite common. The two camps are quite different in structure and complement each other nicely. We have our Complete and Baseball/Softball Skills Camp Bundle for those campers.

My child is attending both camps (Extended Day and Bundle). Is there supervision provided from during this break?
Yes. Direct supervision and activities are provided at no additional cost for this lunch time each day.

Your Baseball and Softball Complete camp is for kids in 1st through 6th Grade (2023-24 school year). My child is in kindergarten. Can he/she attend too?
We are hesitant because inexperienced campers find it to be too overwhelming and still struggle with thrown or batted balls. If your kindergartner has experience playing, then it should work out just fine for the Morning Complete Camp only (not Extended-Day). But please, keep in mind, it is a long session and can sometimes be very warm or cold. In the end, the discretion is yours.

I see there's quite an age range. Are the kids grouped together or are they separated?
Kids are predominantly grouped by skill and age. Common sense and the expertise of our coaches lend itself to appropriate grouping of the kids. Safety and the ability to learn while having fun are the guidelines. Our coaches are very attentive on the first day and throughout camp to appropriate grouping of the campers.

Can I get a receipt?
Please use your credit card statement and/or printed confirmation email as your receipt.

How should we dress for camp and what should we bring?
Dress athletically, ready to play ball! Be prepared for any weather. Bring your glove, cap, a snack (or full lunch if with us all day), plenty of water and sunscreen. You may bring your bat, helmet and other gear too. With anything of value, be sure your name is clearly marked. For catcher camp, we do provide catcher's gear, but you may bring your own.

Do you offer a military/first responder discount?
Yes, if you have a family member who is active or retired in the military or defense department or first responder! Each family member receives $10 off the application fee and this can be used with other discounts (sibling & returner). The discount codes are found on this page above following the question ¡°How much does it cost for camp? Do you offer any discounts?¡± Discount codes can be entered at the final payment page.

We live in a time when kids are pushed to excel in activities younger than ever before. The key with any activity, baseball or fastpitch softball in this case, is to build an enjoyment of the game, with technical training at a pace that matches the natural human developmental process. Teaching fundamentals is terrific, but intense training too early has no benefit. Those that love the game will play and practice it more, ultimately reaching their potential, whether they are limited in ability or the most talented. Kids without love of the game will pull away and sadly, stop playing. Our philosophy is to ensure a true passion is built within every player, while at the same time teaching proper fundamentals and learning the game. We teach fundamentals, lots of game situational concepts and boy do we bring the fun!

Cancellation Policy
We ask for cancellation notice a full two weeks before the first day of your selected camp to receive a full refund. We handle all last-minute emergencies on a case-by-case basis.
