Major League Baseball has reshuffled its umpire roster for this season after the retirements of crew chiefs Ed Rapuano, Tim Tschida and Derryl Cousins.
MLB announced the moves Monday.
Jim Joyce, Ted Barrett and Fieldin Culbreth have been promoted to crew chiefs. MLB also hired Vic Carapazza, Manny Gonzalez and Alan Porter as full-time staff members after they split time between the majors and minors in recent years.
The 66-year-old Cousins worked 4,496 big league games, which had been the most among current umpires and ranked seventh all-time. Rapuano is 55 years old and Tschida is 52.
The 47-year-old Barrett becomes the youngest crew chief in the majors. He is the only umpire to be the plate umpire in two perfect games, including Matt Cain's gem last season.
