Narrative:

I was working local and ground. Small aircraft Y was turning left base runway 13 cleared for touch and go. I put air carrier X into position on runway 9. I cleared air carrier X for takeoff. I looked back to find small aircraft Y and saw him airborne approaching the midfield. Just as I was ready to key the microphone, air carrier X called to say he was aborting takeoff.
