James, who batted .310 in 26 games with the Royals, had been designated for assignment when the Royals called up four rookies from triple-A Omaha on Saturday.
Chamberlain was hitting .350 for triple-A Pawtucket. He hit .119 in 19 games with the Red Sox before being sent to the minors in June.
San Francisco placed left-hander Trevor Wilson on the 15-day disabled list because of a strained rotator cuff. The Giants recalled Stephen Mintz from triple-A Phoenix. . . . Cincinnati starter Jose Rijo plans to play catch Sunday, testing his right elbow. If there’s any pain, he will request surgery.
