Wright has agreed to a new package that will keep him in a Mets uniform through at least 2020, a major league source told ESPNNewYork.com. The deal is worth slightly less than $140 million, the source added.
The sides agreed to the final financial terms in the early morning hours Friday, another source said.
Wright took a physical Monday. The club was just awaiting the blood results in order to announce the third baseman's signing to an extension. A formal announcement of his deal can come as early as Tuesday.
Wright was due to be paid $16 million next season. The new deal should lock in Wright for seven additional years at approximately $122 million.
The total package will surpass the six-year, $137.5 million deal Johan Santana agreed to as a prerequisite of being traded to the Mets.
Wright was in Jacksonville, Fla., over the weekend for the wedding of teammate Daniel Murphy.
Wright, who turns 30 on Dec. 20, is widely viewed as the face of the Mets' franchise and often has expressed a desire to spend his entire career with the organization. He grew up in Norfolk, Va., admiring Cal Ripken Jr. for his lifelong service to the Baltimore Orioles. Teammates R.A. Dickey and Jonathon Niese in recent days noted that Wright would like to be viewed similarly to how Chipper Jones is regarded by Atlanta Braves fans.
This season alone, Wright became the organization's all-time leader in hits, runs, walks and RBIs while being named to his sixth All-Star Game.
Mets officials hope Wright will become an ambassador for the organization after his playing career is over -- a role Hall of Fame pitcher Tom Seaver currently serves.
The signing also is a gesture of goodwill toward the fan base, which was upset by the Mets' lukewarm attempt to re-sign shortstop Jose Reyes the previous offseason, when he hit free agency.
Locking up Wright allows the Mets to concentrate on re-signing another All-Star in Cy Young Award winner Dickey, who is under contract for 2013 at $5 million.
A major league source said Dickey is seeking only a two-year extension on top of his 2013 deal.
The knuckleballer has indicated he will not negotiate with the Mets during the season, so the sides are attempting to work out a deal now.
