At the weigh in today Igarashi was 115lbs, bang on the Super Flyweight limit. The talented Japanese fighter views his future as a Super Flyweight and this will be his third successive bout in, or around, the divisional limit. The division, which is hot in Japan right now, could see Igarashi challenging someone like WBO champion Naoya Inoue or WBA champion Kohei Kono somewhere down the line.
Arizala on the other hand was just 113lbs, only 1lb above the Flyweight limit. For Arizala it was no surprise he'd be "coming in light" considering he is concentrating on the Flyweight division. Had he been the original opponent for the bout there is a chance he may have come in heavier, but given the notice there probably wasn't enough time to bulk up and maintain his natural attributes.
On paper this should be another win for Igarashi however Arizala hasn't taken this bout to lie down and he appeared very relaxed and comfortable at the weigh in. Hopefully he'll put in a solid effort tomorrow as he searches for a career defining victory.
