The Mets announced on Tuesday the signing of six players to Minor League contracts with invitations to Spring Training -- infielders Russ Adams, Andy Green, Mike Hessman and Mike Cervenak, right-hander R.A. Dickey and outfielder Jesus Feliciano.

Adams spent most of the 2009 season in the Triple-A affiliates for the Blue Jays and Padres, batting .294 with 30 RBIs in 84 games. The 29-year-old left-handed hitter has mostly played shortstop since being selected by Toronto in the first round of the 2002 First-Year Player Draft, and he sports a .247 batting average in parts of five big league seasons.

Green appeared in four games with the Mets this past season, and spent most of the year at Triple-A Buffalo, where the 32-year-old utility man batted .259.

Hessman, a 31-year-old who's played mostly third base, spent the 2009 season in the Tigers' Triple-A affiliate, where he finished fifth in the league with 23 home runs, but hit just .217 in 131 games.

Cervenak, a 33-year-old third baseman, played for Triple-A Lehigh Valley of the Phillies' organization this past season, batting .305 with nine homers and 77 RBIs while making his second consecutive International League All-Star Game appearance.

Dickey, 35, made the Twins' Opening Day roster and appeared in 35 games -- compiling a 4.62 ERA in 64 1/3 innings -- and then went 2-1 with a 5.13 ERA while making five starts for Triple-A Rochester.

Feliciano led the International League in hits (154) while playing for Triple-A Buffalo in 2009. The 30-year-old also finished with a career-high 30 doubles and a .311 batting average to win the Sterling Award from the Bisons as the team's most valuable player.
