The decision to promote Mike Trout was based solely on Peter Bourjos' hamstring injury. In other words, it's completely unclear if Trout will remain in the majors following Bourjos' return. The Angels are unsure if Bourjos will require a stint on the disabled list. Regardless, Trout should get the start in center field for all three of Los Angeles' games against the Mariners this weekend, and if he starts out with a bang, it's hard to envision him being sent back to Double-A by a team in a dogfight for the American League West.
