What was the biggest piece of history that happened in baseball in 1990?

Answer by  Padres (7)

Bobby Thigpen recorded his 57th save for that season. This established a new major league single season record. This record stood until 2008 when Francisco Rodriguez topped it with 62 saves. Although the record does not still stand, Thigpen's season is considered the best by a closer.
