At the public work out Machuca was introduced as being a smart intelligent man outside of the ring, with a high level of education. That education was also mentioned as being part of his style in the ring. He confessed that he had to wear glasses outside of the ring but didn't need them whilst boxing whilst also stating that he knew Hasegawa was fast but that his brain would be the key to beating Hasegawa and that he would be trying to counter the experienced Japanese icon.
Ahead of traveling to Japan he had sparred with Francisco Vargas, who recently dethroned Japan's Takashi Miura, and he had also scouted Hasegawa whilst watching footage of his bout with Jhonny Gonzalez. He wants to replicate Gonzalez, and Fernando Montiel, and beat Hasegawa as it will help him become "famous" as a fighter.
Unfortunately whilst he, and his team, was happy to talk to the media he wasn't that willing to show off his ability in the ring and only really put together a short shadow boxing session for the media. It was clear that he wasn't wanting to give too much of his style away, but he did seem confident.
