Royals ace Zack Greinke is expected to make his next scheduled start against the Red Sox on Tuesday. Greinke took a line drive off his pitching arm this week. The shot came off the bat of Detroit's Miguel Cabrera on Thursday. "As long as there are no setbacks, it will be Zack on his regular day," Kansas City manager Trey Hillman told the Toronto Sun. "He felt fine. There's a little bit of swelling in his forearm. It's continuing to go south. We hope that's dissipated in the next 72 hours before Tuesday." Greinke is 14-8 this season with a major league-leading ERA of 2.14.
