Mariners 3B - 2016 Kyle Seager 

While he made his lone career All-Star Game in 2014, his season that occurred two years later was arguably better. It was his highest career OPS, OPS+, batting average, on-base percentage, slugging, WAR and more. 

Finishing 12th in MVP voting, he was a part of the three-headed monster that was the Mariners’ offense in the mid-2010s, alongside Cruz and Robinson Canò. 

For the ‘16 season, he slashed .278/.359/.499 with 30 HR (second-most of his career), 99 RBI and his .859 OPS was the only time of his career that he even marked over .800. 

With 99 total extra-base hits for the year, he was one of the best hitters in the league. His .902 first-half OPS also pointed to the fact that he should have been given an All-Star nod for his production, but history shows no accolades for the third-baseman.
