WEST PALM BEACH — Trea Turner and Bryce Harper went out for pizza Thursday, the night before Washington Nationals position players were officially due at spring training. Fellow pizza parishioners flocked to Harper, who took selfie after selfie.

“I was just sitting there,” said Turner, who reveled in the anonymity. He acknowledged the fact that attention follows success. But he admitted he would rather not have that kind of attention yet.

“For now,” he said. “I’m good.”

Nine months of age, a thick beard, and four seasons of major league experience separate the 24-year-old Harper from the 23-year-old Turner, who arrived at camp with a little more scruff than he sported last year. But while Turner’s ratio of success to attention might never rival Harper’s, that ratio could shift this season.

After he charged into the rookie of the year race with a stellar second half last year, Turner enters this season with as much star power as a few months in the majors can build. He will be the starting shortstop for an annual contender, paired with Daniel Murphy to form one of the strongest offensive double play combinations in baseball. His 2016 second half revealed his ability to hit for high average, steal bases at a high percentage, and hit for some power now and then.

Importantly, Turner also enters this season with a subtle dose of star-like confidence, a quieter kind than Harper’s bravado, a more honest brand than the assuredness Murphy masks with his dogged dedication to humility. For example, when asked if his success last season surprised him, Turner said it surprised him less than it surprised most other people.

Murphy was asked the same general question when he addressed reporters for the first time Thursday. Did he really believe he would sustain his remarkable playoff success of 2015 through the entire 2016 season? Did his push for the National League batting title surprise him?

“You never think you’re going to go and hit whatever, .340, in this league,” said Murphy, who actually hit .347. “It’s really, really difficult to hit a ball at 95 mph, but if you can get it off the barrel at 100, I can speak from personal experience: It’s really hard to catch.”

Murphy is more self-deprecating than some of the other stars in the Nationals clubhouse, more willing to plant a joke like that one about his defense. His ability to catch the ball will once again be secondary to his ability to hit it, a standard that will likely apply to Turner, too.

The Nationals expect errors from Turner, who will effectively be a rookie shortstop – though an eager one, who summed up his enthusiasm for switching back to the position with the words “heck yeah!”

“I worked on it a lot last year,” said Turner, who took ground balls in the infield before games he started in center. “This year, I can put all my focus on it, so I’m excited.”

Murphy, meanwhile, said the glute/hamstring injury that bothered him late last year is healed and no longer a concern. He did more lower body work this offseason than he has in the past to keep the area stable, but has no worries about the trouble lingering. His range, limited though it was at times, should be similar to what he showed at second base last season.

Whatever defense they provide, Turner and Murphy have shifted the focal point of the Nationals’ lineup to the center of the field, where they and newly acquired Adam Eaton seem likely to combat offensive inertia. Last year’s lineup incorporated Murphy and Turner. This year’s lineup, however Manager Dusty Baker writes it out, will depend on them.

While Murphy is a pillar in the middle of the Nationals order for this season and next, Turner seems on the verge of lodging himself as the next Nationals superstar.

Last season, Turner was the rookie. Now, he is the shortstop, and perhaps the leadoff hitter, too. Now, he is a known commodity, a pivotal piece of one of the most potentially productive double play combos in the game. If he plays a full season the way he played the last half one, Turner, like Harper, will not be able to dine undisturbed for long.
