The pitcher formerly known as Fausto Carmona, the current Roberto Hernandez, made the Rays rotation:

Last year the Rays had a lot of success shifting Wade Davis from the rotation to the bullpen, as he went from a mediocre starter to a very good reliever (and then they traded him to the Royals).

This year they’re making the same shift with Jeff Niemann, moving him to the bullpen in an effort to ease his comeback from an injury wrecked 2012 that has left his spring velocity lacking. In his place the Rays have chosen Roberto Hernandez (formerly known as Fausto Carmona) for the final spot in the rotation.

Hernandez only made three starts for the Indians last season, pitching poorly. He struck out two in 14 innings. He was never much of a K pitcher, so the key to his success will be the excellent Rays defense and keeping his walk rate down. He is in the perfect place to make use of his strengths.
