How it unfolded
Both men are southpaws, which meant the usual angle-hunting was off the table and the super middleweight title fight became a question of who could land first and most often. By round six it was Iglesias: he dropped Zaren twice, and in round seven, at 1:31, Zaren's corner threw in the towel. Iglesias, a Cuban fighter based in Germany, improves to 16-0 with 15 knockouts; Zaren, who entered 19-0-1, takes his first loss. Our preview set up the all-southpaw matchup.
What he wants next
Iglesias asked for a unification fight with the other super middleweight champions and named Canelo Álvarez and Christian Mbilli among them. Canelo and Mbilli fight on October 31 in Riyadh for the WBC title. Nothing has been announced.

The undercard
Wilkens Mathieu won the co-main event by split decision over Vladimir Shishkin.
The lesson
Finishing is a skill, not luck. Iglesias dropped Zaren twice in round six and followed it with enough pressure that the corner stopped the fight in the seventh, which is what separates a champion with 15 knockouts in 16 fights from a boxer who wins rounds and lets the finish pass. After you hurt an opponent in sparring, practice the next five seconds, not just the hurt.
Mirror matches punish habit. The fighter who has trained away from his comfort zone finds the finish first.
