Adrian Beltre has a grade 1 calf strain, and the Texas Rangers third baseman will be out indefinitely as the team opts for a conservative approach, per the beat guys on Twitter.
The 38 year old had a setback while running on Saturday, prompting him to get an MRI on Monday. The MRI revealed the strain, which is the lowest grade of calf strain.
This issue has been dogging Beltre since early in spring training, and while he has a history of managing leg issues, those have historically been hamstring related, not calf related.
In his absence, Joey Gallo is expected to continue to get the bulk of the playing time at third base.
