Haren is on his way to Anaheim in exchange for Joe Saunders, Patrick Corbin, Rafael Rodriguez and a player to be named later.
According to reports, the player to be named later will likely be a prospect. Sports Illustrated's Jon Heyman said on his Twitter page that the prospect would come from a 'short list.'
Jeff Passan of Yahoo said on his Twitter that the prospect would not be 2009 first-round pick Mike Trout.
Many thought — even as late as this weekend — that the Yankees were the front-runners to acquire the starting pitcher.
