Brown Mets after they were placed on waivers for the purpose of removing them from the 40-man roster.
The Mets need to begin clearing room because the 40-man roster had been full entering the offseason and prospects need to be protected from the Rule 5 draft.
Matt Harvey and Bobby Parnell returning from the 60-day DL replace free agents Daisuke Matsuzaka and Bobby Abreu. So the subtractions of Brown, Centeno, Rice, Satin, Carlyle and Eveland place the Mets at 34 on the 40-man roster.
Brown, 30, hit .182 with two homers and seven RBIs in 44 major league at-bats this season and was snubbed for a September call-up.
Centeno, 24, hit .200 with two RBIs in 30 at-bats.
