Prior to the 2004 season, he was ranked by Baseball America as the fourth best prospect in the Reds' organization. Moseley came to the Angels' organization in a trade for pitcher Ramón Ortiz in 2004.

Moseley won his first game as the starting pitcher for the Angels in his Major League Baseball debut on July 17, 2006. With injuries to key starters Bartolo Colón and Jered Weaver, Moseley began the 2007 season in the Angels starting rotation. After the return of Jered Weaver, he pitched out of the bullpen in middle relief.
