Atlanta outrighted Hamilton to Triple-A Gwinnett on Sunday, Barrett Sallee of 680 The Fan Atlanta reports.
Hamilton will stick around in the organization as bullpen depth at the Triple-A level after going unclaimed off waivers over the weekend. Before Atlanta dropped him from its 40-man roster Friday, Hamilton made four appearances out of the big-league bullpen and gave up four earned runs on six hits and three walks across 4.2 innings.
