Injury-prone left fielder Carl Crawford was placed on the 15-day disabled list Tuesday by the Los Angeles Dodgers after an MRI revealed a tear in his right oblique. ''I knew I did something to it, but I didn't know quite what was going on,'' Crawford said Tuesday after receiving a cortisone injection. So until I can without having pain, that's when I can start doing other stuff.'' The Dodgers recalled infielder-outfielder Kike Hernandez from Triple-A Oklahoma City to fill the roster spot. This is Crawford's seventh stint on the DL in 14 major league seasons, and fourth since joining the Dodgers in August 2012 as part of a blockbuster trade with the Red Sox that also brought first baseman Adrian Gonzalez and pitcher Josh Beckett to Los Angeles.
