That's encouraging news. Casas has missed more than three months with torn rib cartilage. The Red Sox currently have Dominic Smith and Romy Gonzalez platooning at first base.

Red Sox chief baseball officer Craig Breslow said Thursday on 93.7 FM in Boston that Casas (ribs) is taking full batting practice and could be ready to begin a rehab assignment by the end of the week, Chris Henrique of Beyond the Monster reports.

Red Sox manager Alex Cora said Monday that Casas (ribs) could be close to turning a corner in the recovery process, Ian Browne of MLB.comreports.
