The rumor was first reported by the Tacoma News Tribune and picked up by the New York Post on Monday.
Sexson, who turns 30 on Dec. 29, was sidelined for most of this season with a shoulder injury that limited him to just 23 games, none after May 22.
For the season, his first with the Arizona Diamondbacks, Sexson batted .233 with nine home runs and 23 RBI. He did, however, show flashes of power before going down to injury: Sexson blasted a 503-foot homer against the Chicago Cubs on Apr. 26, the longest home run ever hit at Arizona's Bank One Ballpark.
When healthy, Sexson is one of the league's top first basemen, which makes the Mets' interest logical. The 6-foot-8 slugger is one year removed from a 2003 campaign in which he hit 45 home runs and drove in 124 runs for the Milwaukee Brewers, who traded Sexson to Arizona that winter in exchange for six players.
The Mets are unlikely to count on Mike Piazza's first base experiment as an everyday occurrence in 2005, and with the retirement of Todd Zeile, a first baseman is high on the team's winter wish-list.
