NEW YORK Bud Selig took over a sport with $1.7 billion in revenue, four teams in each year's postseason, economic disparity among the clubs and a fixation on sticking with traditions that dated to the 19th century.
After a decade of maintaining his departure was imminent, the 79-year-old baseball commissioner put his exit plans in writing Thursday and said in a statement he will retire in January 2015 after 22 years the second-longest term behind Kenesaw Mountain Landis.
Selig's revolutionary reign produced an $8 billion industry, interleague play, an expanded postseason and two decades of labor peace. But, he also presided over a canceled World Series and long-running drug scandal.
"He's been the voice of baseball. Some people liked his voice. Some people didn't," Minnesota Twins manager Ron Gardenhire said. "I have a lot of respect for the guy."
Selig has been a bit of the Boy Who Cried Wolf in the past when it came to his retirement. He said in 2003 he would step down at the end of 2006 but has repeatedly accepted new contracts.
Some owners even his wife were skeptical in the past that he really would quit, but this marked the first time he issued a formal statement that he will give up the sport's top job. He even gave an exact date: Jan. 24, 2015.
"I look forward to continuing its extraordinary growth and addressing several significant issues during the remainder of my term," he said.
Selig's length of service and impact on his sport matches those of Pete Rozelle, the NFL commissioner from 1960-89, and David Stern, who is stepping down in February after 30 years as NBA commissioner.
Selig, who took over as acting commissioner on Sept. 9, 1992, in his role as chairman of the executive council, said he will soon announce a transition plan that will include a reorganization of central baseball management. Rob Manfred, baseball's chief labor negotiator, has gained increased influence in recent years, but it's not clear whether Selig's successor will come from within the commissioner's office.
Other MLB in-house candidates include executives Tim Brosnan (business) and Bob Bowman (new media).
Club officials often mentioned include Giants president Larry Baer, Milwaukee Brewers owner Mark Attanasio, Detroit Tigers president Dave Dombrowski and Arizona Diamondbacks president Derrick Hall.
Many speculated Selig wanted to surpass the term of Landis, who served from November 1920 to November 1944.
Perhaps the biggest mark on Selig's tenure was the prevalence of performance-enhancing drugs.
Management didn't have a drug agreement with its players from October 1985 until August 2002, and drug testing with penalties didn't start until 2004. Selig has repeatedly defended his record, saying baseball acted as fast as it could in a matter that was subject to bargaining with players.
"The game has grown under him tremendously. He's made every effort to try to clean the game up," Yankees manager Joe Girardi said.
Selig's tenure also included splitting each league into three divisions instead of two in 1995, when wild cards and an additional round of playoffs were added. Wild cards doubled to four last year, when the postseason stretched to four rounds.
