"Six Degrees of Harry Greb"

[Bundana]

Let's try a game of "Six Degrees of Kevin Bacon" - applied to boxing, of course, and with "The Pittsburgh Windmill" as our subject.

Name the most recent middleweight world champion, who can be linked to Greb in no more than 6 steps (max 5 names between the two), like this:

Recent middleweight champ

Harry Greb

[BattlingNelson]

A poor try here:

Ray Robinson
1: Joey Maxim
2: Gus Lesnivich
3: Tami Mauriello
4: Maxie Rosenbloom
5: Tiger Flowers
Harry Greb.

This should be easy to best.

You're being too hard on yourself, Bat. Ok, there's a better answer than Robinson, but you're the only one who have even tried... so props to you for that!

I believe Antoufermo is the correct answer. Good Job!

(You can never know for sure, if there isn't some super shortcut somewhere - but I'll be very surprised, if there's a more recent middleweight champ, who fits the question).
