The Chicago White Sox were desperately clinging to a ninth-inning lead, hoping for a victory that would put a positive finish on a miserable road trip. Then, something astonishing happened: Thanks to a fine bit of acting by shortstop Alexei Ramirez, the White Sox actually got a lucky break. Pinch-runner Chris Dickerson got lost on the bases and was doubled up for the final out, and Chicago ended a nine-game losing streak by holding off the Baltimore Orioles 4-2 Sunday.
