It's no secret that California is a hotbed for baseball talent. Combine the ideal weather with the massive population and the Golden State has proven golden for professional and college scouts to find talent in droves.

The high school class of 2025 is loaded with talented left-handed pitchers.

While Southern California, as always, is well represented, Northern California has some strong talent on this list, most notably Rocklin's Joey Lorenzini and St. Mary's-Stockton's Tanner Grove.

Here is that list of the top 10 left-handed pitchers in California from the Class of 2025, based on the Prep Baseball Report ranking, with supporting statistics from MaxPreps and scouting data by MLB.com.
