Dubon was optioned to Triple-A Sacramento on Friday.
The 27-year-old was recalled Thursday and went 0-for-3 with a strikeout in a win over the Brewers, but he'll head back to the minors after Evan Longoria (hand) was reinstated from the 10-day injured list. Dubon has hit .333 with 29 home runs, 22 RBI and nine stolen bases in 46 games in the minors this year.
