Moyer, who signed a Minor League contract in June, had a two-start agreement with Triple-A Las Vegas. At the end of the audition, the Blue Jays had to choose whether to place Moyer on the 25-man active roster or grant his release.
Toronto made its decision after watching Moyer surrender 10 runs in 11 innings with the 51s. He also allowed 17 hits while striking out nine and issuing three walks.
The 49-year-old Moyer was signed to provide organizational depth for the Blue Jays, who currently have starters Brandon Morrow, Kyle Drabek and Drew Hutchison on the disabled list. Since that trio went down, though, a new group has emerged to help solidify the starting staff.
Brett Cecil, Aaron Laffey and Carlos Villanueva appear to have relatively secure positions in the rotation right now, which blocked Moyer from being promoted from the Pacific Coast League.
There was no immediate announcement on what Moyer plans to do from here. He began the season with Colorado and went 2-5 with a 5.70 ERA in 10 starts before being released.
Moyer then signed a Minor League deal with the Orioles and made three starts with their Triple-A affiliate -- posting a 1.69 ERA. Baltimore later granted his release as did Toronto and it remains to be seen whether Moyer will attempt to latch on with another organization.
Moyer, a Pennsylvania native, has spent parts of 25 seasons in the Major Leagues. He owns a career mark of 269-209 with a 4.25 ERA with eight different teams.
