History

Historical Context

MLB’s most recent expansion in 1998 added the Arizona Diamondbacks and Tampa Bay Devil Rays, raising the league to 30 clubs after a $130 million fee and a 30-player draft. The Rays’ inaugural 63-99 season set a roster-building template that the Chicago White Sox echoed today by trading infielder Oliver Dunn for left-hander Joe Rock, a strategy rooted in that expansion era.
