It took a few minutes, but soon it was announced that the Red Sox also got a prospect in return: outfielder Carlos Gutierrez. Why did the Red Sox give up on Mayer seemingly so fast? Gutierrez is the exact type of position player prospect the Red Sox have targeted the last few years. Over the last two drafts, the Red Sox have targeted players with good swings that they could try to add some exit velocity to. The Red Sox got a fantastic left-handed reliever in return, and it took about three seconds for Gutierrez to have my attention.
