WASHINGTON -- The Washington Nationals reinstated closer Sean Doolittle and first baseman Ryan Zimmerman from the 10-day injured list on Sunday.
The team also reinstated right-hander Jeremy Hellickson (right shoulder strain) from the 60-day injured list and right-hander (right biceps tendinitis) from the 10-day injured list and recalled three minor leaguers as rosters expanded for September.
Doolittle (6-4, 4.33 ERA) missed 12 games with right knee tendinitis. He ranks third in the National League with 28 saves but allowed 12 earned runs in 10 appearances before going on the injured list.
