Basallo is out of the lineup for Tuesday's game against the Mariners due to left wrist pain, Jacob Calvin Meyer of The Baltimore Sun reports.
According to Jake Rill of MLB.com, Basallo has dealt with some discomfort and pain in his left wrist throughout most of his life, and he was diagnosed with a bony growth in the wrist Monday after the issue resurfaced. The 21-year-old should now have better path to treatment and could look for a more permanent solution during the offseason.
