Major League Baseball commissioner Bud Selig will be offered an extension to his current contract, according to a highly placed source. Baseball executives presume Selig will continue in the job. Selig, 77, has one more year remaining on his current contract and has previously said he intends to retire in 2012. The extension offer will be for at least two years, the source said. It comes at a time when baseball is thriving and has a new labor agreement in place.
