Diaz’s dominance continued at Iowa Western Community College, where he became one of the top JUCO pitchers in the country. His sophomore campaign stood out as he posted an 11-1 record with a 1.52 ERA and a whopping 14 K/9, helping the Reivers to the JUCO World Series and earning NJCAA All-American honors. That performance raised his profile and led to a transfer to Michigan State University’s Division I program.

After transferring, Diaz continued to refine his craft against Big Ten competition, eventually moving to the Spartans’ closer role during his junior year. His 6-foot-4 frame and mid-90s fastball attracted professional interest, leading the Atlanta Braves to select him in the 27th round of the 2019 MLB Draft.

After the lost 2020 season due to the COVID-19 pandemic, Diaz worked his way back into shape in the Braves system, pitching at the High-A and Double-A levels. He was traded to the New York Yankees organization prior to the 2023 season, although his year was shortened by season-ending Tommy John surgery.

Season 2025

That season, his strikeout rate dropped to 7.9 K/9, but this was accompanied by improved command and efficiency, which limited hard contact and allowed him to work consistently in leverage situations. The result was his first 50-plus innings season in professional baseball.

Looking ahead to 2026

After the 2025 season, Diaz opted for free agency and signed with the Arizona Diamondbacks, marking the final stop in a professional journey that tested his ability to adapt. At 27, he profiles as veteran bullpen depth in the upper minors, with the physical tools and resume to potentially break into the MLB late in the season.
