Cordero threw 60 pitches between 45 and 60 feet without feeling any pain. The plan is to play catch every other day for two weeks, and he hopes to start throwing off the mound by the third week.
"Everything felt good. I wasn't trying to blow it all out," Cordero said. "I was a little nervous, too. When you have [an injury] like that, you don't know how it feels until you go out there. My first throw was kind of nerve wracking. I had no pain. The only thing I felt was not throwing for four weeks."
When he returns to game action, which could be by the end of June, Cordero possibly may find himself in a closer controversy. Right-hander Jon Rauch is doing extremely well in the role right now. However, Cordero declined to get involved.
"He is doing a good job right now, and I'm not going to think about it," Cordero said. "I'm not going to worry about it until I get back. Hopefully I can get my spot back after a week of playing some games. It's going to be a tough decision for [manager] Manny [Acta] to make. I've been doing it the last [three-plus seasons], so hopefully I could get that back."
During his career, Cordero has saved 128 games for the Nationals/Expos.
