Analysis:

Xavier Martinez started his collegiate career at Cal State Northridge (CSUN) before transferring to USC for his junior season. During his summer league experience, he started for the Anchorage Glacier Pilots (2022, Alaska League) and relieved for the Harwich Mariners (2023 Cape Cod League). He was recognized as an All-PAC 12 performer in 2024 with 31 appearances, 58 strikeouts, and 26 walks in 48.1 innings.

On the mound, Martinez displays a lean, athletic frame and uses a three-quarters arm slot with below-average command. He utilizes a low-90s fastball and showcases a high-spinning curveball with spin rates occasionally above 3,000 rpm (ranging from 2,800-3,000+ rpm). Martinez also incorporates a changeup and previously utilized a slider in high school. He was known for his multi-inning relief role for the Trojans.
