Tim Beckham, Mariners

After finally realizing his potential with a strong 2017, the 29-year-old Beckham reverted back to his unspectacular ways last year. The first overall selection in the 2008 draft went on to hit just .230 with 12 homers and 17 doubles in 96 games. He owns nearly a 4.5-to-1 strikeout to walk ratio for his career. He has played all over the field but is no better than average at any of the positions.
