Troncoso sent down, DeWitt stays

This one wasn't hard to see coming. Ramon Troncoso has struggled in each of his past two outings, and he hadn't pitched since Friday night. The Dodgers have three long relievers right now in Esteban Loaiza, Hong-Chih Kuo and Chan Ho Park (even though one of them has to fill the fifth starter's role each time through), so they're OK going with 11 pitchers right now. DeWitt probably will still get enough playing time to justify his staying in the majors without hurting his development. ... Another tough break for Ramon Martinez, a really good guy who appears to be nearing the end of his career. His injury turns out to be the same one LaRoche has, and Ramon had the same surgery today that LaRoche had back in March. That's an eight to 10 week rehab, beginning now. He batted .259 in eight games at Las Vegas this year.
