Alonso (elbow) had negative X-ray results after taking a pitch to the elbow and exiting Wednesday's game in San Francisco, Justice delos Santos of MLB.com reports.
EDGE Analysis
That Alonso didn't exit the game immediately after getting hit suggested he avoided a major injury, and the X-ray confirmed as much. He should be considered day-to-day, and it's unclear whether he'll be available for Thursday's series opener in Los Angeles.
