NOTES: Royals OFs Lorenzo Cain and Gordon added a hit before Friday's game. After an appeal, both were awarded hits from last Sunday's game at New York in which Daniel Murphy and Marlon Byrd were originally charged with errors after losing balls in the sun. ... Red Sox RHP Alex Wilson, who went on the disabled list July 9, continues to have problems with his right thumb. "He's having recurring discomfort," Red Sox manager John Farrell said. "He'll have to be re-examined by a hand specialist." ... Red Sox CF Jacoby Ellsbury stole his major league-leading 41st base in the second inning.
