Kenley Jansen couldn't sleep last night.The Dodgers' closer was texting with Dee Gordon, his roommate in the minor leagues, his teammate in the majors, and his nemesis this week when the Miami Marlins swept a four-game series at Dodger Stadium.Like many in the Dodgers' clubhouse, Jansen was stunned by a bombshell that dropped minutes after the Marlins' 5-3 win on Thursday night: Gordon had accepted an 80-game penalty after testing positive for two banned performance-enhancing drugs.
