"My junior year in high school we made the regionals and I started the semifinals and pitched seven innings, allowed one hit in a night game with about 100 pitches," said Billingsley. "The next day I started in right field but our pitcher got into a jam in the first inning and they brought me in with the bases loaded and got out of the jam and went back to the outfield.
"Two innings later, they brought me back in to pitch and I finished up the last four innings. After that, I was tired."
Billingsley said he once made 180 pitches in a high school start. He made 84 Tuesday in six scoreless innings in San Diego. He said he doesn't believe the quick return will be a problem.
"The only change in my routine is that I usually lift twice between starts and this time I'll do it only once," he said Friday. "Or maybe today I'll do a light lift. The week seems to have gone by faster. I'm not worried. My arm feels good. If I had needed an extra day, I wouldn't have gone in and offered to pitch. If my body and arm weren't able to do it, I wouldn't do it."
Billingsley is 5-2 with a 3.22 ERA in 17 games against the Giants, including a shutout July 21.
