Atlanta acquiring Paul Maholm last night makes even more sense with news that Tommy Hanson is headed to the disabled list with a back injury.

Hanson has officially been diagnosed with a strained lower back and revealed that he's been pitching through the injury since the All-Star break, which explains his 7.45 ERA in four second-half starts.

Maholm will take Hanson's rotation spot this weekend and Kris Medlen may get a chance to make multiple starts instead of being one-and-done as a spot starter.
