St. Louis Cardinals — Trevor Rosenthal has been placed on the 10-day DL with right elbow irritation. As we mentioned earlier in the daily update, we expect a committee of Seung Hwan Oh and lefty Tyler Lyons while Rosenthal is out, but we will continue to monitor to see if manager Mike Matheny offers any clarity on the situation.
Updated hierarchy: *Oh | Lyons | Brebbia.
* = closer-by-committee
