Narrative:

I was working final radar combined west/O a handoff person. Cga X was on a 270 degree heading at 7000'. I climbed cga Y to 7000' heading 360 degrees. I then turned cga Y to a 100 degree heading. As cga Y was turning sebnd, I may have lost the 3 mi minimum. I climbed cga X to 11000' then. I should have restr cga Y to 6000' only, but I was somewhat fatigued due to the early am push and am start on my first day back after my weekend.
