Alonso was diagnosed with a right wrist contusion after initial X-rays came back negative, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

This news comes as a major relief after Alonso was hit flush on the wrist and removed from Tuesday's game against the Marlins -- his first since being sidelined with a sore knee over the weekend. While X-rays were negative, he is still dealing with a contusion, so there's still the possibility of Alonso sitting out Wednesday with an off-day looming before the A's weekend set with the Yankees. Look for a further update on Alonso's status during the day Wednesday, but if he's unavailable for the series finale, Ryon Healy would likely fill in at first base.
