JUPITER, Fla. — Once upon a time, as Dusty Baker recovered from knee surgery, he had a t-shirt made up.

My knee is okay so don’t ask me no more,” Baker remembered that t-shirt saying, unclear about whether he was paraphrasing or not. “You get tired of people asking you how you feel. ‘Same way I felt yesterday!'”

Baker tries not to ask Ryan Zimmerman how he feels anymore. Zimmerman told him his left foot, bothered by plantar fasciitis since early last season, is doing well. But the Nationals are managing the chronic condition, which requires Zimmerman to wear special insoles and try to minimize time spent in metal cleats on hard infields.

“He’ll be fine,” said Baker, who said he hopes to get Zimmerman playing Grapefruit League games “in the next couple weeks.” Before games started, Zimmerman went through all the infield and offensive drills with his teammates, though he did do modified conditioning (running in the outfield), while his teammates ran the bases.

Plantar fasciitis pushed Zimmerman to the disabled list on June 11 of last season, and he stayed there until late July. By late August, he’d found his stroke, going on a torrid 10-game tear that ended when he strained his oblique and finished the season on the disabled list because of it.
