1. 2013: 8.6 fWAR
You have to have some crazy numbers to be have an 8-WAR season or better. Well, in 2013, Miggy did just that.
He won the Triple Crown in a different form — the slashline form, to be exact. He led the American League with a slashline of .348/.442/.636 and an OPS of 1.078. His 193 wRC+ was the highest of his career.
In addition to being the second straight year in which he hit 44 bombs, he walked (13.8%) almost as much as he struck out (14.4%). He was just the best hitter on the planet at the time.
He also played third base in 2013, which helped contribute to the higher WAR. He started playing at the hot corner in 2012 after the Tigers signed Prince Fielder. But overall, his offensive numbers in 2013 were just otherworldly.
It may be surprising to some, but yes, Miguel Cabrera was technically better in 2012 than he was in 2013. Pretty much every number backs that up, not just WAR.
