Diamondbacks linked to Japanese superstar in free agency

ESPN’s Kiley McDaniel has linked Kazuma Okamoto with the Diamondbacks in his free agency destination predictions, and that turned heads for Arizona fans. Okamoto brings more than the typical “international star mystery” tag. His resume carries data-driven credibility: consistent 30-homer power, improving chase rates, and a swing that blends lift with adjustability, traits that translate far more reliably than raw velocity or one-dimensional pop. At just 29, he represents the rare free agent whose prime hasn’t already passed. Okamoto leads Japan’s NPB in home runs since he entered the league in 2018 with 247. (Credit: Kiley McDaniel | ESPN)

Strategically, that matters. The Diamondbacks’ emerging core with Corbin Carroll’s electric athleticism, Ketel Marte’s switch-hitting stability, and a rotation with room to grow needs a middle-order anchor who can lengthen innings and punish mistakes late. After losing 3B Eugenio Suárez in a trade at the deadline last season, they will need a new strong bat in their lineup. Okamoto’s profile does exactly that, and unlike many established MLB stars, he fits the franchise’s financial window. Nationally, the league is watching whether a mid-market club can leverage international scouting and development efficiency to compete with big-market muscle.
