Nationals' Ryan Zimmerman: Able to do running drills Sunday

Zimmerman (ribs) was able to run the bases prior to Sunday's game, Bill Ladson of MLB.com reports. "Things are coming along. I'm going day by day," Zimmerman said. "I have six or seven days before I'm allowed to come off [the disabled list]. I haven't done anything to talk about. But [the rib cage] feels good."

Analysis:

He'll still need to swing a bat before the Nats are willing to put a timetable on his return, but assuming he has no setbacks Zimmerman should be back in the lineup next week.
