Though fielding aptitude can be difficult to gauge, these 10 MLB players have distinguished themselves as obvious defensive liabilities. Statistics and good ol' game highlights uncover their specific weaknesses.
UZR (Ultimate Zone Rating) from Fangraphs is insightful. It combines range, errors and execution into one number, which in the following cases will always be negative.
Single-season values, however, can be misleading. A player's UZR from, say, 2010 to the present is much more reliable.
Prince Fielder, Alfonso Soriano and the other individuals included here have all started the vast majority of their teams' games in 2013. Their flaws vary from mental and instinctual to physical and technical. The lone, broad commonality? Below-average performance when outfitted with a glove.
Keep in mind, full-time designated hitters like Billy Butler, Travis Hafner and David Ortiz weren't considered. After all, they don't get opportunities to refute the criticisms against their defense.
But rest assured, pathetic examples abound.
