Pittsburgh Pirates: Is Mitch Keller Coming Up?

The Pittsburgh Pirates look to be shaking up their rotation going into this weekend. Are they going to call up their top pitching prospect?

The Pittsburgh Pirates have some good news coming their way. Right-handed starter Chris Archer is finally coming off the injury list and is joining the rotation. The former Tampa Bay Ray was dealing with a thumb issue on his throwing hand that plagued him his last couple starts. He is supposed to start tonight against the Diamondbacks.

This still leaves a spot in the rotation. The other injured pitcher Jameson Taillon, has just recently been moved to the 60-Day Injury List, meaning he will not be back for a while. This leaves a rotation spot for either…
