Washington Nationals place Adam Eaton on 10-Day DL; call up Moises Sierra; DFA Miguel Montero; reinstate Matt Wieters...

Davey Martinez told reporters last night he wasn’t sure Adam Eaton would end up on the Disabled List after Eaton suffered a bone bruise in his left ankle, but the 29-year-old Nats’ outfielder did say what the manager didn’t, a DL stint was likely.

“We’re going to reevaluate everything in the morning,” Martinez said. “We don’t really know where he’s at right now, but I know tomorrow they’re going to talk to the doctor and let me know what’s going on.”

“Bone bruises, I guess, I don’t know, it seems like they take a little longer,” Eaton said, “so I would expect that, but I’m not 100% sure of what their decisions will be. I’m not sure.”

This morning, the Nationals announced that Eaton will go on the 10-Day DL with 29-year-old outfielder Moises Sierra, who signed a minor league deal with the Nats this winter, called up from Triple-A Syracuse to join the bench in the nation’s capital.

In addition, the Nationals recalled and reinstated Matt Wieters from his rehab assignment, and designated catcher Miguel Montero for assignment.

Martinez had previously discussed the possibility of keeping three catchers on the major league roster.

“We have some decisions to make when Miggy and Wieters both come back,” he said earlier this week. “We haven’t decided that yet. Good possibility we keep three catchers, we don’t know that yet, but we’re going to talk about it.”

Instead, they decided to DFA Montero, making room on the 40-Man Roster for Sierra, and it will be Pedro Severino, who’s impressed since he was called up when Wieters was placed on the Disabled List, remaining in the majors after he was optioned to Triple-A Syracuse at the end of Spring Training.

Sierra hasn’t played in the majors since he was 25, and played 96 games with the Chicago White Sox and Toronto Blue Jays in 2014, after debuting with the Sox in 2012.

Eaton, who lands on the DL after fighting his way back from last April’s season-ending knee and ankle injuries, talked last night about how he thinks things will play out for him over the next week-plus.

“I think our mindset is a week of kind of relaxing,” he explained, “and then going from there with speeding everything up. The nice thing about it is it only hurts when I walk and jog, lifting is fine, sprinting is fine, throwing is fine, hitting is fine, so I think once we realistically get to walking and jogging and [get] that bone healed, we should be able to get off and running relatively quickly, no pun intended, with rehab and then getting back out there, so very weird rehab process.”
