The crafty left-hander began the season as the Colorado Rockies #2 starter, and had a 3.14 ERA through his first five starts, but Coors Field eventually got the best of him. Moyer put up an 8.64 ERA in his final five starts, averaging only five innings an outing, and was released by the Rockies earlier this week.
In his short time with the Rockies, Moyer became the oldest pitcher in MLB history to win as a starter. If he makes the Orioles roster at some point this season, Moyer will have the chance to hold the record in both leagues.
The signing marks a return to the Baltimore organization for Moyer, who spent three years with the Orioles (1993-1995) back when Bill Clinton was still in his first term.
Moyer will start for the Orioles' Triple-A affiliate in Norfolk on Saturday.
