Brash (elbow) is expected to play catch Tuesday with a trainer, Shannon Drayer of 710 ESPN Seattle reports.
The right-hander is still expected to be weeks away from a return, but Tuesday represents an important step in his recovery. If Brash is able to come out of the session without any setbacks, he'll likely begin a deliberate process of building up his workload while managing the medial right elbow inflammation he's been experiencing.
