Northwest Diamond Series is a series of baseball tournaments in Vancouver, WA and Portland, OR. Our mission is to provide a first class tournament experience for all.  All games are played on full AstroTurf fields at local high school and college facilities. And unique to this event, the tournament format is double-elimination with either a 4 or 5 game guarantee.

WEATHER NOTES

With AstroTurf Diamond Series turf on all fields, all will be done to get games in with few exceptions:

  • If severe weather is forecasted, game times may be adjusted to best fit the forecasted weather pattern.  
  • If lightning is seen by tournament officials or umpires, a 30 minute delay will start immediately after each lightning flash. Both game and/or pregame activities will be suspended for 30 minutes.  Game times will be adjusted accordingly.
  • Heavy rain may cause a game delay, or even a cancellation.
  • Should weather or weather related circumstances cause a cancellation, tournament fees will be refunded as follows:
    • 1 game played: 50% refund.
    • 2 games played: no refund. 

Again, we will do all we can to get your games guaranteed played.
