Originally, he was expected to compete for a spot in the starting rotation, but that possibility was lessened dramatically when the Royals re-signed Jeremy Guthrie and traded for James Shields and Wade Davis. So the Royals decided to release Moscoso, giving him time to catch on with another club before Spring Training ends.
Moscoso was claimed off waivers from the Rockies on Nov. 2. His busiest season as a starter was 2011, when he was 8-10 with a 3.38 ERA in 21 starts and two relief outings for the Athletics.
