The Angels are in a tight enough spot in the wild-card race that it makes sense for them to add a significant player such as Zack Greinke, who easily could be worth two extra wins to the team from now through the end of the season over the disastrous Ervin Santana. Greinke also gives the team a better fourth starter in October than Jerome Williams, assuming the team reaches the playoffs.
