Donald Fehr has led the MLB players union for some 26 years, and before March of next year, he’ll step down.

Subject to approval by the union’s executive board, he will be succeeded by union general counsel Michael Weiner, his longtime heir apparent. Weiner will head negotiations heading into the expiration of the current labor contract in December 2011.

“I have no hesitancy in recommending to the players that he be given the opportunity to do this job,” Fehr said. ESPN.

Fehr has been a staunch advocate for the players, and a general thorn in ownerships’ side. Thus, he’s done his job well.

The best news in all of this? The next dude is named “Weiner.” Score.
