PHILADELPHIA -- Bryce Harper is seven for seven so far on Philadelphia restaurants, and he hasn’t even tried Zahav yet.

Harper has immersed himself in everything Philadelphia since he signed a 13-year, $330 million contract with the Phillies on March 1, particularly since the team returned from Clearwater, Fla., on March 25. He wore a Phillie Phanatic and Gritty “Pulp Fiction” T-shirt to Citizens Bank Park on Opening Day. He wore Phanatic cleats on the field. He crushed his first home run Saturday, bringing his first curtain call from a raucous sellout crowd. He hit his second Sunday, helping the Phillies sweep the Braves.

“Getting here, the last couple days have kind of been like a little storm,” Harper said Sunday. “Trying to move into a place, get a place, get all of our stuff unpacked. I’m just trying to enjoy it as much as possible.”

Harper’s Philadelphia beginning has been a lovefest, but he returns to Washington on Tuesday to play his former team in his former ballpark, when the Phillies open a two-game series against the Nationals at Nationals Park. The Nationals selected Harper with the first overall pick in the 2010 Draft. He played seven seasons with the Nationals, becoming one of the most iconic professional athletes in North America, winning the 2015 National League Most Valuable Player Award and helping the Nats win the National League East title in 2012, ’14, ’16 and ’17.

"If you would have told me five years ago I would be walking into Nationals Park as an opposing player, I would’ve told you that you were crazy," Harper wrote in an Instagram post Tuesday. "Five years later, I’m doing just that.

"I remember the first day I walked into Nats Park. My first base hit. My first home run. And, of course, my first standing ovation. Nationals fans delivered that first ovation."

Nobody knows what to expect Tuesday, not even Harper.

“I’m sure some cheers, some boos as well,” he said. “It’s part of the game. It’s part of sports. I’ll always remember and cherish all the screaming and yelling and the exciting times that we had the last seven years.

“I wish them nothing but the best, all the players in that clubhouse. It’s a great fanbase, a great city to live in. But [I'm] just excited to go back and excited to compete.”

Harper has been inside the visitors’ clubhouse a few times, but he acknowledged it will be strange to walk past the home clubhouse Tuesday afternoon.

“It’s something that I’m going to have to get used to,” he said.

Pretty soon it will become second nature to him. A 13-year deal with the Phillies ensures that.

“Obviously an emotional game for Bryce, knowing the kind of competitor he is,” Rhys Hoskins said about his expectations for Tuesday.

Phillies manager Gabe Kapler is excited to see what the atmosphere will be.

“I'm also a baseball fan, and I love all human psychology,” he said. “I love to see how people respond to moments like that, the players, the fans and the cities.”

So what does he think? Do Nationals fans cheer Harper for the great memories he created? Or is he booed for signing with a division rival?

“Very strong standing ovation,” Kapler said. “My reaction is that fans understand players' contributions. And I don't think his contributions to D.C. and the Nationals can be discounted. They are really important for that city and for the history of that franchise.”

“I think it will be mixed just because of his stature and the type of player he is,” Jake Arrieta said. “The hype around him, deservedly so. Superstar, 26 years old, leaves a team to go to another team in the same division. I think it will be mixed, but they should give him a really good ovation for what he was able to do with that organization for the last six years.”

Said Nationals shortstop Trea Turner: “Seeing highlights of him now is a little weird. It’ll be weird seeing him come out of that dugout and get cheered or booed by our fans, or this and that.”

Harper’s presence in Philadelphia for the next 13 years should only add to the rivalry between these two organizations. Harper was once the face of the Nationals. Now he is wearing Phanatic cleats, socks and T-shirts. He is bowing to Phillies fans in right field.

He is loving the City of Brotherly Love.

“I’m a Philadelphia Phillie,” Harper said. “I’m excited to be a Phillie. I’m excited to be in the city of Philadelphia, and we’re going back there and playing a good team in the Nationals and we’re going to do it a couple more times this year and a couple more times in the next 13 years. So just excited to get back and get playing.”
