Holt was outrighted to Triple-A Louisville on Monday.
Holt made it through waivers unclaimed, and he'll now head into the offseason off the major league roster. The 27-year-old appeared in 106 contests this year, but he hit just .235 and didn't get a plate appearance over the final 11 games of the season, so it's unclear what the interest will be when he hits free agency following the conclusion of the World Series.
