The combination of Kevin Correia, Paul Maholm, Charlie Morton, James McDonald, and Jeff Karstens has an ERA of 2.91 in the month of May. To go along with the stellar ERA, they have a K/BB ratio of 2.32, another really strong number. Seeing those numbers, you would expect the Pirates to be a lot better than 12-11 during the stretch, but the offense just hasn't been there to support them. Hopefully that side of it will come around soon.
Here is the detailed start-by-start breakdown of the Pirates starting pitching performances this month. Enjoy.
