PHOENIX -- With the end of Class Triple-A Reno's season, the Diamondbacks promoted five players from the Aces to their major-league roster and also reinstated pitcher Andrew Chafin and catcher Chris Herrmann from the 15-day disabled list.

The five players being called up include four who have spent time in the major leagues this season -- left-handed pitcher Steve Hathaway, right-handed pitcher Dominic Leone and outfielders Mitch Haniger and Peter O'Brien -- and one who will be in the majors for the first time -- right-handed pitcher Matt Koch.
