Now that Rich Hill finally got past an arm injury, he's got a knee problem that might ruin his bid to pitch for the Los Angeles Dodgers in the postseason. Hill struggled with his control during his first start since June 19 and hurt his left knee in the process, a development that took the edge off a 4-2 victory over the Baltimore Orioles on Thursday night. ''It was an MCL strain, something that he dealt with initially early in spring training,'' manager Dave Roberts said.
