This is his second year working with the Cal Poly Baseball Team as a Field Student Manager.

Rosas has been around the sport of baseball for as long as he can remember. He began playing when he was 3 years old and fell in love with the game. In his childhood, he played recreationally until eventually competing at the high school level and still loves being around the game, even if it is off of the field.

Outside of sports, he was a part of his school’s Link Crew program, where he would help incoming freshmen transition from middle school to high school.
