1. SERGIO MARTINEZ
The Puerto Rican promised the upset when he challenged WBC middleweight king, and undisputed division leader, Sergio Martinez in June 2014. Few believed him. The ageing Cotto was chasing a title in a weight class for which he was deemed too small, against an opponent presumed too big. But the veteran, under the watchful eyes of new trainer Freddie Roach, made a mockery of the consensus, and battered Martinez into defeat in 10 rounds.
