City in California (8)
'city in california' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pasadena that I've seen before include "City in Los Angeles County" , "California city of the Rose Bowl stadium" , "US city" , "Californian city" , "place in California" .)
(Another definition for sandiego that I've seen is " Where navy may be found".)
