Aroldis Chapman was scratched from his planned Arizona Fall League start on Monday because of a sore left shoulder. The Reds' left-hander made two relief appearances for the Phoenix Desert Dogs last week in the AFL.

"He had a little inflammation in his shoulder," said Reds general manager Walt Jocketty. "It was probably from trying to do too much, too soon. He didn't do a lot before going down there."

Chapman, who threw 2 2/3 innings of relief and gave up one hit and one run, was pitching in the AFL to begin a transition towards becoming a starter next season for Cincinnati. He was expected to start some games and stretch out his arm in Puerto Rican winter ball next month.
