Brett Gardner, Yankees

Not counting his first year in 2008 when he made just 141 plate appearances, Gardner posted his lowest average (.236) and OPS (.690) of his career in 2018. In 140 games, he also totaled 12 home runs, 20 doubles, and 16 stolen bases. The 35-year-old remains excellent in the field even as age is creeping up on him.
