Mattingly still hadn't named a Tuesday starter following the Dodgers' 3-2 loss to the Phillies on Monday.
Mattingly added the team was being cautious with scratching Billingsley from his scheduled start on Sunday. After Monday's game, the manager said the team doesn't want to push the panic button and feel forced to start Billingsley and risk further injury. Mattingly said he doesn't foresee any time needed on the disabled list and expects Billingsley to miss just this one start.
As far as Tuesday's starter, Mattingly said there is a chance the team will call somebody up who is on the 40-man roster, and he planned to talk with general manager Ned Colletti after Monday's game. He ruled out reliever Jamey Wright, who hasn't started since 2007 and threw one inning Sunday.
That callup could be Stephen Fife, who was scratched from his scheduled start on Monday for Triple-A Albuquerque. Fife is 7-5 with a 4.53 ERA in 18 starts with the Isotopes this season.
A likely scenario would be the team calls up Fife to start Tuesday and sends down either Josh Wall or Shawn Tolleson, who pitched two innings in relief on Monday. Javy Guerra, who is expected back Tuesday or Wednesday from visiting his father in Mexico, would likely return from the bereavement list on Wednesday, when the team sends Fife back down after making the spot start.
