Astros placed OF Fernando Martinez on the 15-day disabled list, retroactive to March 27, with a strained oblique. Martinez has been dealing with the injury for over a week now and had to be scratched from Thursday's lineup. Now that he's been officially ruled out for the start of the season, look for the Astros to target Casper Wells or Julio Borbon should the become available. J.D. Martinez has been recalled in a corresponding move.
