While Padres manager Bud Black is not ready to put odds on the competition for the final spot in the team's rotation, he did seem to indicate Brandon Morrow and Odrisamer Despaigne might be a little ahead of Robbie Erlin and Matt Wisler , per U-T San Diego.
"I think we're going to look at them all, but Morrow and Despaigne have a little something to them," Black said. "It doesn't hurt Matt to go back to the minors. Robbie Erlin was in our rotation last year, made some starts and pitched well at times. He's still developing. I don't know if there's a front-runner, but you can maybe say that Morrow and Despaigne are out there just a touch."
