Bryce Harper doesn’t just like playing first base.

“I love it,” he said Monday afternoon.

But he loves winning more.

And, of course, he wants to win a World Series. He openly talked about riding down Broad Street in a victory parade on the day he arrived in Clearwater back in March 2019.

Harper confirmed his will to win in conversations with Don Mattingly in recent days.

“You serious about playing the outfield?” Mattingly asked.

“Yep,” Harper said.

Harper confirmed his will to win again in a text message to Dave Dombrowski late Sunday night.

“If anything pops up, make the move,” he told the team’s president of baseball operations.

So, Monday morning, Dombrowski made the move, bringing three-time batting champ Luis Arráez and reliever Caleb Kilian to Philadelphia in a deal that sent two pitching prospects to the San Francisco Giants.

Harper, 33, has been the Phillies’ first baseman since 2023.

Starting Tuesday night, when Arráez is expected to arrive, Harper will become the Phillies’ right fielder. He has not played that position since early in 2022, but has long said he would move back there if it meant clearing a spot for a player who could help the Phillies win a World Series.

“I know everybody thinks it’s crap when I say it, but it’s not,” Harper said. “Any chance we have an opportunity to win – I’d do anything for this organization and they know that.

“I’m at a spot in my career where I don’t have to do it. I don’t have to play another position. I’m very comfortable at first base. I love first base. I love being on the infield. This is something I’m doing for the team. That’s how I feel about it. I don’t have to do it, but I want to win. I want to win more than anybody so I’m trying to do that. I hope it helps.

“It helps us get the guy we need. (Arráez) can hit righties and lefties. I think he will help a lot. He’s a guy that has won batting titles, somebody who will put the bat on the ball. He’s an exciting player. He brings a lot to our lineup. He’s got that hit tool. He’ll be really good for us. I’m definitely excited.”

Arráez is the centerpiece of Dombrowski’s trade deadline, but right-hander Kilian and left-hander Brooks Raley, acquired from the Mets for two minor-league pitchers, should be solid additions to the Phillies’ bullpen.

The Phillies’ offense needs a spark. The team ranks 29th in the majors with a .304 on-base percentage and has been held to one or zero runs 26 times, third-most in the majors. Arráez, a lefty hitter who seldom walks but seldom strikes out, currently leads the National League with a .324 batting average. He is a lifetime .318 hitter with a career on-base mark of .360. Mattingly would not say where he intends to hit Arráez, but it’ll likely be first or second.

“I’m definitely excited to have Luis,” he said. “Without putting too much pressure on him, he’s kind of like the modern-day Tony Gwynn or Wade Boggs, a guy that just hits, wins batting titles and continues to do it. Obviously, he’s a huge addition to the lineup.”

The addition, Mattingly said, does not happen without Harper’s willingness to move to the outfield for the rest of the season. (Harper said he will move back to first base next season.) The Phils had been mostly looking to add an outfield bat, but Harper’s openness to changing positions allowed them to broaden the scope of their search for offense. Harper immediately began conditioning his arm for a longer throw during pre-game work Monday.

“The key to this all is Harp,” Mattingly said. “Him being willing to do it, being serious about it, was the key to opening our mind to do different things so we could get away from an outfielder and open our mind to different guys.”

Arráez has played first base in his career, but he prefers second base and that’s where he will play for the Phillies. Others, besides Harper, made sacrifices to accommodate Arráez. Second baseman Bryson Stott will move to third base and Alec Bohm will move across the diamond to first base.

“Anything to win,” Bohm, who has played first base in the past, said Monday.

Harper had big praise for Stott’s willingness to move.

“Bryson Stott is an incredible second baseman,” Harper said. “For him to think about it shows how important this team is to him. Bohm, too. The big one is Stott. He’s one of the best in the game. I applaud him for doing it. He’s super athletic. I think it will be easy for him. I think it shows what we want to do as a team and an organization and that’s win.”

Stott played shortstop for the Phillies’ NL championship team in 2022 and moved to shortstop when the team signed Trea Turner before the 2023 season. Turner has struggled defensively and might not be long for shortstop. But the team has not considered moving him to the outfield this season.

“I’m not afraid of our defense like this,” Mattingly said. “Bohmer will be fine at first, Stott will be good at third. He can play anywhere.

“This just makes us better. We have to figure out ways to be consistent with our scoring and things like that so I have no concerns about moving him. You add a guy like Arráez, it makes you better up and down the lineup. We’re adding to our offense.”

Dombrowski made an excellent trade, picking up All-Star closer Jhoan Duran, at last year’s deadline. Last week, Harper created a stir by challenging Dombrowski to get this year’s team help at this deadline.

How did he do?

“I think he’s done a great job,” Harper said. “Arráez, Raley, Kilian. It’s been a good deadline.”
