For the better part of his career, Mariners fans were all happy about Kyle Seager. Through his first six full seasons, he was a .264/.333/.450 hitter. He averaged 25 HR and 85 RBI a year, while playing solid defense (1.1 dWar per year average), and even earning a Gold Glove in 2014 in his lone All-Star season.
However, things have changed a bit since the 2017 season. His average has dropped to .227, even though he is hitting more HR and driving in more RBI on a per-game basis.
