Worth noting

• Nats right-hander Doug Fister is slated to throw about 45 pitches over three innings in a simulated game on Tuesday. Fister, on the disabled list with a lat strain, threw his first simulated game last Thursday, working two innings.

• Williams said that catcher Wilson Ramos, on the disabled list with a broken hamate bone in his left hand, is on schedule or maybe a little ahead of schedule in his recovery. Ramos suffered the injury in the season opener on March 31, and after having surgery, was expected to miss four to five weeks. According to Williams, Ramos has been hitting balls off a tee with a modified bat that has the weight taken out of it, and is trying to get his hand strength back.

"They take the [hamate] bone out, the bone's still raw, so it's really nothing wrong with him at this point," Williams said. "It's more pain tolerance and stuff like that, but at least he's got a bat in his hands and he's able to grip stuff and start to do some strength stuff, so it's good."

Williams also said Ramos has been working hard to stay in shape during his DL stint but likely will need plenty of at-bats during a Minor League rehab assignment before he returns.
