NAGOYA, Japan — Yoshiki Takei went down in the first round and never got on track as he lost his WBO bantamweight crown Sunday to Mexico’s Christian Medina at IG Arena.

Takei (11-1, 9 KOs), rated No. 2 by The Ring at 118 pounds, was recently in a perfect position to challenge countryman Junto Nakatani in a three-weight unification showdown. However, last month, Nakatani relinquished his IBF and WBC titles and is focused on competing at junior featherweight (122).

Medina (26-4, 19 KOs) hurt him badly in the first and scored a stoppage at 1:21 of the fourth round. He has posted five wins in a row since losing a decision to former world titleholder Ryosuke Nishida in August 2023.

Undercard results:

STRAWWEIGHT: Ryusei Matsumoto TD 5 Yuni Takada (1:26)
