Reds left-hander Aroldis Chapman made his Arizona Fall League debut Monday.

He pitched one hitless inning for the Phoenix Desert Dogs. He walked one and struck out one. He threw 16 pitches, eight of which were strikes. Chapman will pitch again Thursday and Monday.

He is building up his innings as part of his conversion back to starting. After the outings in the AFL, Chapman will pitch in winter ball.

RED SOX: Ben Cherington is set to become the new general manager today, replacing his former boss, Theo Epstein.

Cherington's promotion from assistant general manager will be announced today at a news conference. It had been expected for several weeks while the Chicago Cubs were working out details for Epstein to join them. On Friday, both teams announced that Epstein had resigned from the Red Sox to become president of baseball operations for the Cubs.

The teams said then they would delay any news conference until today, a day off after Game 5 of the World Series.
