NASHVILLE, Tenn. -- The Mets announced their new contract with third baseman David Wright Tuesday, finally making official one of the most important signings in franchise history.

Wright's eight-year, $138-million deal will keep the homegrown star under team control until 2020.

The Mets will announce the deal in a news conference Wednesday at the winter meetings.

"I've grown up in this organization and made lifelong friendships with teammates, uniform personnel and front office staff," Wright said in a statement. "I'm grateful for the opportunity to finish what I've started and help bring the Mets and our fans a World Series title."

Wright thanked the Mets' ownership group, which made him a first-round selection in 2001, the start of a career that has resulted in six All-Star appearances.

Wright, who turns 30 later this month, owns the franchise record in hits.

"We're thrilled for the organization and our fans that David will be a Met for many years to come," said Mets chief operating officer Jeff Wilpon. "As great a player as David's been with us on the field -- one of the greatest and most popular Mets ever -- he's been equally outstanding in the community."
