Mount Si Baseball is teaming up with Seattle Mariners Ticketing for our 2026 MSHS Community Day—coming June or July to T-Mobile Park!

We’re updating our ticketing approach:

• Warmer weather

• No conflict with HS baseball season

• Lower ticket prices to make it easier for more families to join

High School Baseball Classic at T-Mobile Park

Mariners ticket sales enables Wildcat Baseball to participate in the High Baseball Classic at T-Mobile Park for an experience the players will never forget.

In order to ensure future Wildcats can play in this event, we need to sell 1,000 tickets.

Last year thanks to you, we reached our goal. In 2026 we remain committed to ensure our long history of access to this experience and look forward to reaching out goal.
 

Mount Si will play in the 2026 HS Baseball Classic
T-Mobile Park | Date/Time TBD
