Left-handed reliever Frankie De Los Santos, activated from Durham's disabled list June 27 and demoted to high-Class A Charlotte, is back with the Bulls.
To make room, Durham has put catcher Craig Albernaz on the disabled list.
De Los Santos threw three shutout innings and allowed one hit in two appearances with the Stone Crabs. He went on Durham's DL on May 10. He also made appearances with the GCL Rays on June 21 and 24, giving up two runs in 3 2/3 innings.
