Pretty hard for me to narrow it down to 3, but here goes:

Mikey Garcia, beats Lipinets, Linares and Loma

Oscar Valdez, beats Quigg, love to see him fight JoJo Diaz and then unify with the Santa Cruz/ Mares winner.

Usyk, beat Breidis, Gassiev, then picks up the WBA title of Charr to set up 2019 at heavyweight.
