The Japanese former amateur stand out will be up against the out of form Mexican Delia Lopez (10-6-2, 5), who has lost her last 3 and 4 of her last 5.
Aged 39 this is potentially the final bout of Yoshikawa's career, if she loses, and she will turn 40 next June. During her professional career she has claimed an OPBF title at Light Flyweight, failed in a challenge of the WBA female Minimumweight title and controversially claimed the WBO female Light Flyweight title, which she lost in her first defense.
As for Lopez, a former Mexican Light Flyweight champion, the bout will be her first for a world title, and at 41 her career has certainly seen better days. She's a 16 year professional, who has shared the ring with the likes of Anabel Ortiz and Jessica Nery Plata, and although once a good fight her recent form suggests her career really is all over as a genuinely notably fighter, and another loss will be expected here.
