PORT ST. LUCIE — In something of a dress rehearsal for next week when he will address his full squad for the first time, Luis Rojas plans to speak with the Mets’ pitchers and catchers Wednesday before their initial spring-training workout.

The rookie manager will provide a blueprint for camp — including a gradual progression in workouts to ensure players don’t burn out early — but may also dive into the big picture and what he expects from the Mets as a unit in 2020.

“We expect to be a contender,” Rojas said Tuesday in his first spring-training press conference. “We know how all the teams are prepared. We are going to be in a tough division and we are going to face some tough teams this year on our schedule and we know that. We feel we are built to win.

“We have a great roster. We have great position players with versatility. We have a great starting rotation with pitchers that have the history, Cy Youngs, World Series winners and a bullpen with a lot of history saving games, being closers, so it’s a team that is built to win. Right now, the thing that is going to keep us moving and moving to the direction we want to go, is spring training. It starts [Wednesday].”

Rojas, named to the job just three weeks ago following Carlos Beltran’s departure for his role in the Astros’ illegal sign-stealing scheme, will be a familiar face to most in the clubhouse. Not only did the 38-year-old Rojas serve as the team’s quality control coach last season, but he spent eight seasons managing in the minor leagues for the Mets, with many of these players under his command.

“Luis is a very open-minded guy,” Michael Conforto said. “He’s really big on the back-and-forth. He’s really big on the communication and always has been that way since I first played with him in the playoffs in Low-A the first year I got drafted.”

Rojas has been charged with guiding to the postseason a team that rebounded in last season’s second half to finish with 86 victories. The Mets have missed the playoffs the past three years despite a starting rotation that ranks among the best in the major leagues, spearheaded by two-time defending NL Cy Young Award winner Jacob deGrom.

The lineup features Pete Alonso, who established a major league rookie record by hitting 53 homers last season, and Jeff McNeil, who contended for the batting title for most of the season before a late-season dip derailed him.

“I’m very comfortable where we are as a team,” Rojas said. “I am very comfortable leading the guys and the main reason for that is the coaching staff. They are such a great coaching staff and they have been working in collaboration almost the entire offseason. You almost feel like we were attached. It’s up to speed because of the great coaching staff we have. The relationship with the guys and knowing the guys is real helpful.”

It’s a staff that includes new additions Jeremy Hefner (pitching coach), Hensley Meulens (bench coach), Tony DeFrancesco (first-base coach) and Brian Schneider (quality control). Returning coaches include hitting coach Chili Davis, third-base coach Gary DiSarcina and bullpen coach Ricky Bones.

Those lieutenants will largely oversee Rojas’ first spring training as commander. It will come against the backdrop of a renovated facility that is receiving $57 million in improvements.

“[Wednesday] is a big day,” Rojas said. “The biggest talk is when the full squad gets in the facility, that is when we are going to talk as a whole, as an organization. But [Wednesday] as an organization and having our pitchers and catchers here, we are also going to talk about setting the tone and breaking ground and the new facility.

“This great facility, great clubhouse and new grounds we have on the field are going to give us more versatility to get our drills going. I am really happy for it.”
