DALLAS -- Move over (to third base), Hanley Ramirez.

As long as he passes a routine physical, Jose Reyes will become the Marlins’ new shortstop.

Reyes and the Marlins agreed to terms on a six-year deal that will reportedly pay him $102 million, the largest contract the Marlins have ever given to a player.

“Done deal,” said a source with knowledge of the agreement.

Reyes, the National League batting champ last season with a .337 average with the Mets, agreed to join the Marlins after the team sweetened their initial offer to an amount he couldn’t refuse.

The Marlins have been courting Reyes since one minute after midnight on Nov. 3, the first time free agents could start talking to other teams.

By increasing their offer to Reyes, they knocked the Mets out of the running to hang on to their shortstop. The Mets were reportedly willing to give Reyes no more than five-year deal worth $75 to $80 million.

With Reyes moving to South Florida and joining the Marlins in time for the opening of their new ballpark, incumbent shortstop Hanley Ramirez will move to third base, albeit reluctantly. Sources have said that Ramirez is not thrilled with the move.

But the Marlins have no intention of trading Ramirez.

Reyes’ contract includes a seventh-year team option with a buyout of $4 million, a source said.

Reyes has had a history of leg problems, which have made him a frequent visitor to the disabled list. But the Marlins are confident that Reyes can be the player who appeared in no fewer than 153 games for the Mets from 2005-08. Reyes played in 126 games last season.

The agreement comes one day before the start of the winter meetings, where the Marlins are expected to officially announce the signing of closer Heath Bell to a three-year, $27 million contract. And the Marlins aren’t done yet.

They’re expected to continue adding players and raising total payroll to close to $100 million next season, a source said.

Starting pitching could be the team’s next focus. The problem is that the market for starters is both thin and pricy — in many cases, outlandishly so — and extremely competitive. Most contending teams are looking for starting help.

“It’s tough to trade for starting pitching and it’s tough to sign,” said Larry Beinfest, Marlins president of baseball operations. “I would say it’s the toughest area to secure.”

The Marlins have already been exploring trades, checking with the Oakland A’s on Gio Gonzalez and Chicago Cubs on Matt Garza. They have extended an offer to free agent lefty Mark Buehrle and met with another free agent southpaw, C.J. Wilson.

But, so far, the rotation remains unchanged, and the Marlins know they must make improvements in that area if they intend to make inroads on the pitching-rich Phillies and Braves in the National League East.

With Josh Johnson idled most of last season with a shoulder injury, the Marlins’ starting staff was an unremarkable 42-60 with a 4.23 ERA and totaled the fifth-fewest innings of any NL club. Was it not for the late-season success of Javier Vazquez, those numbers would have looked even worse.

Alas, Vazquez is expected to retire, although he has yet to say so officially.

The Marlins are expecting the healthy return of Johnson, who began his offseason throwing program this past week. The rotation should also include mainstays Anibal Sanchez and Ricky Nolasco, although the Marlins listened on offers for Nolasco at the winter meetings last year, and the Marlins could try to deal Nolasco and apply his 2012 salary ($9 million) elsewhere.

The Marlins also have a decision to make on Chris Volstad, who has yet to live up to his first-round draft status on a consistent basis. Because Volstad is arbitration-eligible for the first time and stands to see his salary climb to about $2.5 million, the Marlins could decide to non-tender him at the Dec. 12 deadline.

Sources said the front office has impressed the need for starting pitching first and foremost upon owner Jeffrey Loria, who has been hands-on in all offseason roster dealings so far.

Another free agent that could interest the Marlins is Hiroki Kuroda.
