No. 7: Jimmie Foxx, 1938
The first ever Boston Red Sox player to win MVP, Foxx's 1938 season was his third MVP in his, in my humble opinion, underrated career. Foxx really dominated the 1938 campaign for Boston, leading the AL in two of the three Triple Crown categories (50 home runs was mince meat compared to Hank Greenberg's 58), along with slugging, on-base percentage, and OPS. Foxx racked up 7.4 WAR (another league-best mark) and received 19 of 22 first-place votes, cruising to this MVP award.
It's truly a testament to the seasons above Foxx's in this list that they beat out this dominant campaign. This is the season that I had the toughest time placing on this list, but it ultimately ended up at #7 because it just didn't feel like the competition from the rest of the league made it all that interesting. It's one of the most dominant seasons in Red Sox history still, but ultimately there are seasons that are better from an analytical standpoint that have to go higher.
