ISLANDERS FIELD (LATHROP), CA. - The inaugural Northern California Rising Stars Showcase had 35 players take part in as players were put through traditional workout that included the 60-yard sprint, a round of batting practice, defensive workouts at respective positions (multiple spots for a few players), and concluded with main diamond mound bullpen sessions where the pitchers' stats were compiled.

Note: All showcase videos have been added to player profiles. We will post reports by position as the week moves along (corner INFs, outfielders, MIFs, 2023/2024 pitchers, 2025 pitchers). The players listed here are ordered by their peak throwing velocity, followed by their EV if their throwing mph was the same.
