Honorable Mention
All underlying data used in this analysis is available in The Baseball Scholar Data Library.

Ortiz’s best season has to be 2006. 54 HR’s 137 RBI’s 1049 OPS. Just because his WAR was higher in 2007 doesnt mean it was his best year.
WAR was one of several metrics I used to compile these. wRC+ and wOBA were two other highly weighted metrics. None of those three metrics factors in RBI. I also didn’t use OPS because it uses SLG which incorrectly weighs hits.
Having said all that, I wouldn’t argue for one of those two over the other.
How do you leave Yaz’s 1967 off? Not even on the bench? His 12.5 WAR was the second highest single season in history.
