With the recent addition of Kwang-Hyun Kim to the 10-day IL, the St. Louis Cardinals have just three healthy members of the rotation. Adam Wainwright, Carlos Martinez, and John Gant as the top three options do not inspire a lot of confidence. They are much better as back-end options in the rotation. Additionally, Johan Oviedo has yet to prove that he is ready to claim a rotation spot in just his age-23 season. However, for the time being, this is what the rotation looks like.
The Cardinals do need to figure out who their fifth starter will be while Kim is injured (hopefully for the 10-day minimum).
