As you all know by now, as Jrsyeagle reported in the comments, Logan Kensing was sent down to make room for Josh Johnson.
The Marlins optioned pitcher Logan Kensing to Class AAA Albuquerque following the game to make room for Josh Johnson, who will be added to the roster today.
Much the same as Fishcrazy, this was a bit of a surprise to me. Kensing has been having control problems but I didn't think he was the next one in line to head to the minors. Although I'm not sure Albuquerque is the place to go to work on control issues, but if you can pitch there, you can pitch anywhere.
