The big one that I can think of is the Bannerwood-centric one that has the usual players in it - Taylor, Chaffey, Stars, Portland Baseball Club, Langley Blaze, etc.
There's another one in July but it doesn't sound like the ones you're talking about.
At any rate, these things are a little overrated anyway. Ability tends to win out over time as long as the athlete is playing consistent HS/Summer ball and attends 1-2 low cost showcases here or there (Area Code Games tryouts and Mariners Scout Team tryouts are always free and worth going to - there should be a Diamondbacks Scout Team as well this year).
