ATLANTA -- The San Diego Padres have activated right-hander Trevor Cahill from the 10-day disabled list and optioned right-hander Kevin Quackenbush to Triple-A El Paso.
Cahill is scheduled to start in Sunday's game against the Atlanta Braves.
Cahill allowed three runs, two earned, in 5 2/3 innings in his only start of the season, a loss to the Los Angeles Dodgers, on April 5. He was placed on the disabled list the following day with a lower back strain.
Quackenbush pitched a scoreless inning against the Braves on Friday in his only appearance after being recalled from El Paso.
