Nick Cafardo of the Boston Globe writes that Felix Doubront "the sleeper choice of many" in the Red Sox organization to win a spot in the starting rotation. Doubront had some injury issues last year but pitched well in the minors when healthy, posting a 3.96 ERA, 1.23 WHIP and 8.6 K/9 rate. Since he's out of options, the lefty will make the team as a reliever if he doesn't win a spot in the rotation. Though he does have some upside, he's got a few ahead of him in the pecking order for a rotation spot, so he'll have to pitch really well in spring training to break camp as a starter.
