In a bullpen session last week, Olsen had a difficult time getting loose.
"He was going to throw a bullpen session the other day," manager Jim Riggleman said. "He didn't feel really good. He has some aches and pains that indicted that trying to get him up in the bullpen just wouldn't work. It's not working for Scott."
Olsen, who was not available for comment, got off to a great start this season, but he was hampered by shoulder injuries that shelved him for a good portion of the season. After coming back from the injury, Olsen was hit hard and was demoted to the bullpen early in September. In two relief appearances, he allowed one run in six innings. Despite his success out of the bullpen, Olsen expressed displeasure being a reliever.
Olsen most likely played his last game as a member of the Nationals. He is arbitration-eligible and will likely be non-tendered after the season and become a free agent.
