Alonso had an MRI performed on his strained right forearm after Tuesday's win versus the Rockies, MLB.com reports. Alonso has already required a stay on the disabled list this season due to a sore right wrist, and manager Bud Black relayed Tuesday that the first baseman's ailment is in the same region. The exam should shed light on the extent of the injury, but consider Alonso day-to-day until his fate is revealed. His removal in the fourth inning prompted Tommy Medica to man first, which may also be covered by Jacob Goebbert or Yasmani Grandal.
