In a bantamweight bout, Perez and De la Rosa meet to keep ascending the rankings. Perez was last seen losing in controversial fashion to Joseph Benavidez, as he was hurt by a headbutt and punched in the back of the head numerous times. De la Rosa last won an uninspiring decision. Perez was a huge flyweight and will be the bigger man here even though he is the one moving up in weight. De la Rosa has some decent boxing and good grappling skills, but I cannot help but feel Perez is better everywhere. He is bigger, more powerful and has an array of submissions to go with it. The pick here is Perez to win by submission after rocking De la Rosa on the feet.
