Ace Reese, the Mariners’ 2026 first-round draft pick, stepped onto the field at T-Mobile Park on Monday. The young outfield prospect spent time at Pike Place Market, the Space Needle, and talked with Mariners officials. He also swung in BP on the field. Seattle called his number four days earlier with the top slot from Walton High School in Marietta. His advisor, Scott Boras, connected with team personnel to lay out the club’s draft plans for Reese’s development.
