2026 Seattle Summer Review - Statistical Analysis

August 7, 2026
Dylan Grenz
Assistant Scouting Director

On Tuesday August 4th, Prep Baseball Washington hosted the Seattle Summer Review at Island Crest Park in Mercer Island, WA. Prep Baseball scouts evaluated high school athletes in the 2027-2030 graduating classes, with several strong showings throughout the event.

Summer events serve as an important tool for both Prep Baseball scouts and college recruiters, who will subsequently create lists of prospects to follow as they plan their remaining summer coverage. We often tend to see prospects' best showings at Summer ID events, as players are fresh off playing for their respective high schools and are in the routine that consistently playing in-game offers. Standout performances can lend invites to some of the summer's top events, including the 2026 Pacific Northwest State Games.

Earlier, we released our Quick Hits, detailing scouting notes on standout players from the event. Today, we unveil our Statistical Analysis, looking at leaders in major stat categories. Stay tuned in the coming days for complete post-event coverage. For all other post-event content, click here.
