Asche re-injured his right oblique on a swing-and-miss during a minor league game Saturday, Ryan Lawrence of the Philly Voice reports.
Asche was already ticketed to start the year on the disabled list, but now might be sidelined into the month of May. The Phillies are expected to go with Tyler Goeddel and either Cedric Hunter or Wil Venable in left field while Asche is out.
