Thoughts on the Roberto Duran vs Vilomar Fernandez title bout in 1977.

Duran had a succession of defenses in 76/77 against defensive fighters - runner Lou Bizarro, spoiler Edwin Viruet and Vilomar Fernandez. Vilomar was the best of that bunch and did have some early success in the fight before Duran ground him down and Fernandez collapsed as much through exhaustion as from any one punch.

Here's my card:
Roberto Duran v Vilomar Fernandez

1 10-9
2 10-9
3 9-10 (close)
4 9-10 (close. he's a slippery ****er is Vilomar)
5 10-10 (ref tells Fernandez to fight)
6 10-9
7 10-9
8 10-9
9 10-9
10 10-9 (Duran starting to wear Fernandez down)
11 10-10
12 10-9
(118-112)
13 Duran KO Fernandez

 

Anyone know why Fernandez fought a 1972 trilogy against Jose Resto? I know nothing about Resto, but he has a poor record according to boxrec.
Was there a reason they fought three times so close together? Controversy? Fernandez won all 3 apparently, just seems weird.
