The Phillies selected Gilbert's contract from Triple-A Lehigh Valley on Saturday, Scott Lauber of The Philadelphia Inquirer reports.
Gilbert was acquired by the Phillies from the Reds back in May. Across his 26 outings with Lehigh Valley this season, he's registered six saves with a 2.45 ERA, 1.03 WHIP and 45:6 K:BB across 33 innings. Tyler Phillips was optioned to Lehigh Valley in a corresponding move.
