Brad Kilby is back in Sacramento – for now.

One day after pitching a career high 3 2/3 scoreless innings for the Oakland A’s, Kilby was optioned to Triple-A Sacramento to make room for reliever Michael Wuertz to come off the disabled list.

Kilby, a Laguna Creek High School graduate, went 0-0 with a 2.16 ERA in five relief appearances.

He allowed three hits and struck out three against Toronto last Sunday in the longest outing of his brief major-league career.

The left-handed reliever struck out eight overall and walked none in 8 1/3 innings.

Kilby did not allow a run in four of his five appearances.

The 27-year old had a 1.69 ERA in five relief appearances with the River Cats before his promotion to Oakland.
