WASHINGTON — Nationals center fielder Adam Eaton tore a ligament in his left knee and his season is likely over, the team confirmed Sunday.

General Manager Mike Rizzo said Eaton has a “full thickness” ACL tear, plus a meniscus tear and a high ankle sprain.

“His return to this season is unlikely, but we don’t know until the doctors get in there and we’ll see what the surgery leads us to believe,” said Rizzo, who added the surgery date is not set.

In Friday’s 7-5 loss to the visiting New York Mets, the 28-year-old Eaton stepped awkwardly on the bag when he beat out a throw to first in the ninth inning.

“Just trying to make something happen,” Eaton said. “Kind of got outside my zone there and lunged a little bit at the bag. It’s part of the way I play and it’s unfortunate I got snake bit a little bit there.”

RANGERS: Texas claimed infielder Pete Kozma off waivers from the New York Yankees and will make a move to add him to the 25-man roster once he reports to the club.

Kozma was designated for assignment by the Yankees on Friday when shortstop Didi Gregorius was activated from the 10-day disabled list after recovering from a right shoulder strain sustained while playing for the Netherlands in the World Baseball Classic.

ORIOLES: First baseman Chris Davis was removed from the starting lineup against the Yankees, two days after he was hit on the right elbow by a pitch from New York’s CC Sabathia.

Davis was in the original lineup batting fifth.

Trey Mancini took over at first base and was dropped down one slot.

WHITE SOX: Right-handed pitcher James Shields, on the disabled list for the first time in his career, threw on Saturday and reported no problems with his strained right lat. After playing light catch for about 40 throws, he said that the way his arm reacts will determine if he will need a rehab start before joining the White Sox.

Tigers: Center fielder JaCoby Jones went 1 for 7 in a rehab doubleheader for Triple-A Toledo on Saturday. Jones, who went on the disabled list on April 23 after being hit in the mouth by a pitch, was making his first rehab appearances.

BREWERS: Slugger Ryan Braun left Milwaukee’s 4-3 win over Atlanta after six innings with soreness in his right arm and tightness in his right trapezius, a large muscle that extends from the shoulder into the upper back.

He said he didn’t expect to go on the disabled list, but said he might be out “at least a couple of days” because it was hurting to throw. “There’s a couple things in my arm, hopefully not too bad, but probably more than a day or so,” he said.
