Ryan Mattheus met with Nationals team physician Wiemi Douoguih about his chest discomfort on Saturday with the hope of being cleared to resume, but will have to rest a few more days. Although the right-handed reliever is feeling better, the discomfort from what was diagnosed as costochondritis, an inflammation of rib cartilage, has not completely disappeared.

“I feel really good,” he said. “It feels out of there pretty much. Still a little lingering stuff but 100 times better. It’s going in the right direction so I just have to wait and see when they clear me.”

Mattheus hasn’t thrown in about a week, when he first felt the chest pain following his second bullpen session of the spring. After a rough 2013 season, the right-hander felt confident this spring and eager to reassert himself in the bullpen. Now, he must wait.

“There’s nothing they can do to actually fix it,” Mattheus said. “It takes time. They’re being cautious. So, hopefully we can ramp up a throwing program from here in a few days.”
