Al Haymon is finally starting to stock up on Eastern European talent.

BoxingScene.com has been advised that Ukrainian middleweight prospect Sergiy Derevyanchenko (2-0, 1KO) has come on board with the influental adviser/manager. The Ukrainian fighter is promoted by Lou DiBella, who is close friends with Haymon.

Derevyanchenko competed in the 2008 Olympic games. He won a bronze medal at middleweight at the 2007 World Amateur Boxing Championships. In that competition, he lost a decision to current middleweight contender Matt Korobov, who goes for the WBO title against Andy Lee on December 13th.

He spent several years competing in the World Series of Boxing and was virtually unstoppable - going 22-1 in four WSB seasons. During his successful run, some dubbed him the "King of WSB."

Haymon works with over 130 fighters - including Floyd Mayweather Jr., Amir Khan, Leo Santa Cruz, Deontay Wilder, Omar Figueroa, Robert Guerrero, Adrien Broner, Marcos Maidana, Erislandy Lara, Errol Spence, Peter Quillin, Lucas Matthysse, Adonis Stevenson and many more.
