GIF: Jose Iglesias' defensive wizardry in Tigers-Red Sox ALCS Game 5

Red Sox-Tigers ALCS Game 5: Follow live | Napoli HR | Ross trucks Avila

Here's an example of why advanced defensive metrics are much better in judging defensive value than fielding percentage (via Deadspin.com):

That is Tigers shortstop -- and defensive whiz -- Jose Iglesias flashing his outstanding range and making a ridiculous catch in left field. But if you only look at the play by play log, you'll see this:

David Ortiz :Strike looking, Ball, Ball, Strike swinging, Ortiz popped out to shortstop.

Had Iglesias missed the ball, it would have been called a single, not an error.

Context.
