On April 25 1989, The Mariners trade their ace, Mark Langston, along with minor leaguer Mike Campbell to the Expos for Brian Holman, Gene Harris, and 6′ 10″ southpaw Randy Johnson. The left-handed ‘Big Unit’ will become a mainstay in Seattle’s rotation for a decade, compiling a 130-74 (.637) record, and next season will throw the first no-hitter in franchise history.
