1990 Oakland Athletics season

Eight of the Athletics' nine main postseason starters (R. Henderson, McGwire, Canseco, McGee, Steinbach, Randolph, Baines, and Lansford) played in at least one All-Star Game between 1988 and 1990.

Welch would finish the season with both an MLB-leading 27 wins and a 2.95 ERA; this performance was strong enough to net the 1990 Cy Young Award.

The Athletics' bullpen was led by superstar closer Dennis Eckersley, who posted a microscopic 0.61 ERA while recording 48 saves.
