NEW YORK (AP) -- Curtis Granderson is heading across town, where the New York Mets hope his home run swing won't suffer at Citi Field.
The free-agent outfielder agreed to a $60 million, four-year contract with the Mets, according to a person familiar with the situation. But he surpassed 40 homers in each of his previous two seasons in pinstripes.
The move marks general manager Sandy Alderson's most expensive free-agent signing - by far - after three years of bargain shopping as the Mets rebuilt.
A three-time All-Star, Granderson provides proven thump from the left side of the plate to complement right-handed hitter David Wright in a lineup that managed only 130 home runs last season - tied for 25th among 30 major league teams.
New York also signed free-agent outfielder Chris Young to a $7.25 million, one-year contract this offseason. He figures to fill a corner spot with the Mets, who plan to use defensive whiz Juan Lagares or Young in center.
New York's outfield combined to hit .238 this year (29th in the majors) with 50 homers (tied for 24th) and 209 RBIs (16th), according to STATS. He had 43 homers and 106 RBIs in 2012, taking advantage of the short right-field porch at Yankee Stadium.
The Mets hope his power will translate to spacious Citi Field, where it's more difficult to clear the fences.
Granderson's numbers have declined the past two years, down to a .317 on-base percentage and .407 slugging mark last season. He also is prone to strikeouts - whiffing 364 times from 2011-2012 - and joins a Mets lineup that fanned 1,384 times this year, tied with Atlanta for most in the NL.
But his bat is a significant upgrade for the Mets, starved for offense following their fifth straight losing season since moving into Citi Field. New York was unable to overcome all the injuries, missing the playoffs for only the second time in 19 years.
Granderson's agreement with the Mets was first reported by the New York Post.
