6. Norm Cash, DH, 54.6 fWAR
Cash takes the DH spot in the lineup, though he played first base for most of his career. You could really put anybody at DH.
Cash's career was headlined by his 1961 campaign where he hit 41 homers and put up an insane 10.2 fWAR. Unfortunatley for him, some guys named Roger Maris and Mickey Mantle were going after Babe Ruth's single-season home run record that year. Maris of course broke the record with 61 bombs, while Mantle hit 54. Cash ended up finished fourth in AL MVP voting that year.
That 1961 Tigers team won 101 games, but finished eight games back of the Yankees for the AL pennant. Times were tough in the age of no playoffs.
Cash went on to have several more good seasons, but never quite lived up to that 1961 perfomance again. Still, his career was good enough to log up over 50 WAR for his career, which is still very impressive.
