Worth noting

• Reliever Ryan Mattheus was feeling better on Thursday, a few days after being diagnosed with costochondritis, an inflammation of the cartilage that attaches the ribs to the sternum. The righty has been doing some light running and increased activity in the weight room, "taking baby steps," as he said.

Mattheus will see team physician Dr. Wiemi Douoguih when he arrives at Nats camp on Friday, and he hopes to find out when he can begin throwing and how he'll be able to progress from there.
