Cecconi was optioned to Triple-A Reno on Thursday, Alex Weiner of ArizonaSports.com reports.
Cecconi was recalled Sept. 1 and allowed seven earned runs over 3.2 innings while in the majors. Cecconi has bounced between Reno and Arizona several times this season, so it's possible that he could return to the big leagues in the final days of the regular season.
