Nationals outfielder Adam Eaton has a torn ACL and will miss the rest of the season, Fox Sports’ Ken Rosenthal reported Saturday.

Eaton sustained the injury in Friday night’s 7-5 loss to the Mets when he stepped awkwardly on the bag while beating out a throw to first in the ninth inning. He then collapsed and needed assistance off the field.

The Nationals initially announced earlier Saturday that Eaton would go on the 10-day disabled list with a left knee strain. They also have since called up outfielder Rafael Bautista from Triple-A Syracuse.

The Nationals acquired Eaton in a trade with the White Sox in December in exchange for pitching prospects Luca Giolito, Reynaldo Lopez and Dane Dunning.

The 28-year-old Eaton was hitting .297 with a .393 on-base percentage and 24 runs scored for the 16-8 Nationals.

Michael A. Taylor replaced Eaton in centerfield during the Nationals’ 5-3 loss to the Mets on Saturday.
