[1] In 2009, Palmer would come on as a fifth starter, as the Angels starting rotation struggled to overcome injuries and the death of rookie Nick Adenhart.

Palmer made his Angels debut on April 23, 2009, earning the win after pitching six innings, giving up five runs on six hits, three walks, and one strikeout.

He continued in the Angels starting rotation amassing a 7-1 record until he was moved to the bullpen on July 1, 2009 when Ervin Santana returned.

[2] In 2010, Palmer was seen as a possible fifth starter after Angels ace John Lackey signed with the Boston Red Sox.

[3] However, the signing of Joel Piñeiro diminished any chances of Palmer in the starting rotation, and he returned to the bullpen for the 2010 season.

On December 18, 2012, Palmer signed as a minor league free agent with the Los Angeles Dodgers.

During spring training, he tore the medial meniscus in his left knee, ending any chance he had to make the Dodgers roster.
