Reddick has been diagnosed with a fractured left thumb, Jane Lee of MLB.com reports.

EDGE Analysis

This is a huge loss for the A's as Reddick entered Thursday leading the club in batting average (.322), OBP (.394), and hits (47) and he was near the top in nearly every other major offensive category. He suffered the injury Thursday on a stolen base attempt in the seventh inning against the Yankees when he appeared to jam his hand on the base. According to Lee, Reddick will see a hand specialist Friday to determine the amount of time he'll miss, but with a fractured thumb, a stint on the disabled list seems almost inevitable. Chris Coghlan, Tyler Ladendorf, and Matt McBride are all candidates to take over in right field while Reddick is on the shelf.
