Mariners 1995 Randy Johnson
Another pitcher who’s best season comes down to his Cy Young Award-winning and second-place Cy Young finishing season, this time being given to the former.
In the ‘95 season, Johnson led the AL in win percentage (.900), ERA (2.48), strikeouts (294), ERA+ (193), FIP (2.08), WHIP (1.045), H/9 (6.7), HR/9 (0.5) and SO/9 (12.3).
In every single conceivable way, it was one of the single-most dominant single-season performances by a pitcher ever, making it an easy choice for the all-time Mariners rotation.
