MLB Trade Rumors is reporting that Chris Paddack has been placed on the 15 day Injured List. The corresponding transaction is a call up of Ronny Henriquez. With the Monday off day, Ober can start on Thursday in Arizona on regular rest. Boushley and Dobnak would also be on regular rest to start Thursday, while Varland and Festa both pitched "within the last few days" and would not be available to start Thursday. That obviously doesn't mean they couldn't start Ober on Thursday and bring someone up to start Friday or Saturday if they wanted to stretch the rotation a day. My guess is he Henriquez is up because he can be easily sent back down on Thursday or after the Arizona series, and that they will call up a starter for one of the games in Seattle The corresponding move for a starter call up would be either sending Henriquez back to AAA or perhaps putting Thielbar on the IL.
