Nine of Eckersley's seasons were spent in Oakland, where he made the transition from starter to closer with unparalleled success. From 1988-92, he averaged 44 saves per season while helping the A's to four American League West titles, three AL pennants and a World Series championship in 1992.

His best season was in 1992, when he recorded 51 saves in 54 opportunities and posted a miniscule 1.91 ERA. For his staggering numbers, Eckersley was honored with both the AL Cy Young and Most Valuable Player awards.
