Mariners' Logan Gilbert: Throws another bullpen session

Gilbert (elbow) threw a 25-pitch bullpen session Saturday, Shannon Drayer of SeattleSports.com reports.

Gilbert threw off a mound for the second time since landing on the injured list in late April, though he didn't increase his pitch count. It's a positive sign that he's been able to throw off a mound two times in the span of five days, but the Mariners haven't yet provided a clear timeline for his return. Per Daniel Kramer of MLB.com, Gilbert will require another bullpen session before progressing to live batting practice.
