Once Diaz found his groove, he was landing often with hard, accurate punches to the head and body of Santana. Santana was still applying a lot of pressure and pushing the pace and forcing Diaz to work very hard.

In the seventh round, Santana was really rocked but Diaz was unable to put him down with a flurry of shots. Santana was able to recover and made things very close with his pressure and constant activity in the remaining three rounds.

The scores were 98-92 three times, and 97-93 twice (five judges used in the tournament).
