The Nationals have placed first baseman Ryan Zimmerman on the 15-day disabled list with plantar fasciitis and recalled outfielder Matt den Dekker from Triple-A Syracuse, the team announced on Thursday afternoon.
Zimmerman missed Sunday and Wednesday's games, as he rested during an extended slump. He has been dealing with pain in his left foot since mid-April.
Zimmerman, 30, is hitting just .209 with a .265 on-base percentage. He has a .611 OPS through 56 games this season, the lowest of his career.
Before sitting out Sunday's game against the Cubs, Zimmerman spoke about the injury and said he thought he would be able to play through it.
"That's no excuse. If it was at a point to where it was hindering me, then I shouldn’t play.”
Zimmerman joins teammates Jayson Werth, Stephen Strasburg and Doug Fister on the disabled list. Craig Stammen was also lost for the season with a forearm injury back in April. The team has missed Anthony Rendon for the first third of the year and outfielder Reed Johnson has been injured, as well.
Tyler Moore will likely fill in while Zimmerman is out. Moore is batting .181 with three homers and 10 RBI through 40 games this season.
den Dekker made the team's Opening Day roster, but has appeared in just four MLB games this season.
