What will Adam Eaton do with a full season if he stays healthy in 2019?

Adam Eaton started Saturday night 5 for 12 (.417/.600/.833) with two doubles, a home run, six walks, three Ks, and one stolen base in seven Grapefruit League games. He was 0 for 2 with a strikeout before he was lifted from what ended up a 2-1 loss to the Miami Marlins.

Eaton talked at the start of Spring Training this year about the joy of going through a normal offseason routine for the first time in a few offseasons.

Eaton, 30, arrived in West Palm Beach a year removed from surgery on his ankle and close to two years removed from a full ACL tear, meniscus tear, and a high ankle sprain suffered on a play at first base a month into his first season in D.C. in 2017.

“You’ll manage your whole life with this injury,” Eaton told reporters, “but there’s been no rehabilitation this offseason. It’s been strength. A normal offseason. But continued body maintenance.

“We’ve talked at length the last two years about how this will give longevity to my career because I’m forced to do more body maintenance and take a lot more time out for that.

“It’s been a focus on making sure I’m ready, and probably in a better way than I have been in the past.

“It’s been a good strengthening offseason, and I feel strong. I’m just ready to get after it.”

Davey Martinez, who managed a player that arrived in camp with a limp, had surgery on his ankle early, and didn’t look 100% all summer, talked last week about what he had in the right fielder now that Eaton is seemingly healthy and ready for the start of his third season in the nation’s capital.

“He’s been great,” Martinez told MLB Network Radio hosts Jim Bowden and Steve Phillips.

“Last year, he was hurt. This year he came to camp — he was here in January — and he looks phenomenal. I think you’re going to see the Adam Eaton that the Washington Nationals [traded for]. He’s been that guy so far. He gets on base, he’s a pesky hitter, he knows when to bunt, he knows when to do everything.”

In the 118 games he has played over his first two seasons in D.C., Eaton has a .300/.394/.422 line with 25 doubles and seven home runs in 477 plate appearances.

Martinez said he wants to have Eaton hit second in the lineup this season, after he penciled the outfielder in as the leadoff hitter most of the time when he was available in 2018.

“Things are going to be a little different for him,” Martinez explained.

“I want him to hit second in our lineup, I really do, because when you’ve got [Trea] Turner up in front of him, he’s going to get a lot more fastballs. He’ll let him run, and also too he has the hole open, the first base hole open, and he loves it. I talked to him about it and he said, ‘I would love to hit second.’ And it takes the pressure off him.

“I said the biggest thing is to keep you healthy, and it takes the pressure off him wanting to go out there and try to steal 40 bases, and I told him, I said, “We need you healthy, we need you to play defense, we need you to get on base, we’ve got two guys behind you that are going to hit behind you that will able to drive you in, but we need you on the field.”

Martinez talked early in Spring Training about wanting to have a more consistent day-to-day lineup in 2019, after mixing things up over the course of his first season on the bench.

“We’ll mix it around,” he said, “but what I want to do honestly this year, is if these guys are healthy have a constant lineup, because I really believe that you get to understand how they’re pitching you guys, and a lot of guys talk about sequences and how they pitch guys in certain situations, and if a guy is hitting behind one guy constantly, you kind of know what kind of pitches you’re going to get, so for the most part I want to kind of keep our lineup the same.

“Like I said, it all depends on who’s off and who’s not, and which guys are really swinging the bats well and which guys aren’t.”

After watching his players in camp for a few weeks, the second-year skipper was asked last week if he has a better idea of how he’s going to line Eaton and everyone else up.

“Right now, if everybody stays healthy, things are looking good with [Trea] Turner, Eaton, [Juan] Soto, [Anthony] Rendon, [Ryan Zimmerman], [Brian] Dozier, one of the two catchers [Yan Gomes or Kurt Suzuki], [Victor] Robles, and Michael [A. Taylor]. Those are the guys that we have. And then you get guys like Matt Adams, who’s going to play quite a bit. Howie [Kendrick] who can fill in and play quite a bit.

“So I really believe that this year, with the additions we have and the guys we had last year, as long as we stay healthy we’re going to be in great shape.”
