The 49-year-old Moyer said in a news conference Wednesday that he still had hopes of continuing his career elsewhere but his immediate plan was to return home and attend a son’s high school graduation.
Rockies manager Jim Tracy told Moyer of the team’s decision in a meeting earlier Wednesday.
After missing all of the 2011 season while recovering from reconstructive elbow surgery, Moyer signed with the Rockies and made the team with an impressive spring training. He became the oldest pitcher to win as a starter on April 17, when he led the Rockies to a 5-3 win over the San Diego Padres.
Moyer was 2-5 with a 5.70 ERA in 10 starts.
