"I don't want to do anything to jeopardize the rest of my career but also want to get on the field and play," Werth told James Wagner of the National Post.
"It's a balance. … As soon as I'm ready, I'll be back. … My goal is Opening Day. If I can't make Opening Day in D.C., then I want to make opening day in Boston. I'm going to try to be back as soon as I can without doing something stupid."
Werth underwent surgery to repair the AC joint in his throwing arm on Jan. 9, with an estimated recovery timetable of two-to-three months.
The Nationals open their season April 6 against the New York Mets and travel to Philadelphia for a three-game set with the Phillies before heading to Boston.
Werth appeared in 147 games last season, hitting .292/.394/.455 with 16 home runs and 82 RBIs.
