Myers will bat in the leadoff spot on Thursday as San Diego goes up against Atlanta starter Julio Teheran.
The Padres optioned right-hander Kevin Quackenbush to Triple A El Paso in order to make room for Myers on the roster.
Quackenbush pitched an inning, giving up two hits in relief in Wednesday's 4–1 loss to the Braves. He is 1–1 with a 3.10 ERA in 19 appearances this season.
During his three-game rehab assignment with El Paso, Myers hit .333 with one home run.
Myers, 24, has a .291 batting average and led the Padres in hits and runs scored at the time he was put on the DL.
He has five home runs and 19 RBIs in 32 games this season for the Padres (30–31), who are in third place in the National League West.
