Rob Manfred has been promoted to Major League Baseball's chief operating officer, which may make him a candidate to succeed Bud Selig as commissioner.
The sport's No. 2 post had been open for three years. Paul Beeston served in the role from 1997-02, then was replaced by Bob DuPuy, who left in October 2010.
Selig, who has headed baseball since September 1992, said last week he intends to retire in January 2015, though some owners remain skeptical.
