Associate Scout

As we conclude 2025, Prep Baseball Washington continues our series of Player Spotlights. This series aims to highlight standout performers at our top invite-only events, including the PNW State Games, Future Games, and West Coast Super Sophomore Games. Prep Baseball spotlights aim to showcase players that Prep Baseball Scouts felt showed standout tools, large improvements in overall game, or potential upside moving forward. College coaches and recruiters should be sure to keep an eye on these prospects in the coming months.

Today, we spotlight '28 INF Liam Sirianni. The Mercer Island infielder showed well in his first Prep Baseball event, including a productive set of in-game looks after a strong workout. 

A 5'11 prospect, Sirianni's workout was highlighted by exit velocities up to 89.9 MPH and a 7.2 run time. Below is a complete breakdown of the prospect, including video and stats from the event.
