The Giants hold a collective .241 average during day games, which ranks 12th in the National League, compared to their NL-leading .277 average during night games.
"I think if you ask most of them, they'd say they prefer night games," manager Bruce Bochy said before Sunday's game. "They get to sleep in and go through their routines a little bit easier compared to coming in early and trying to get ready. But some guys prefer day games. I know I do."
The disparity between day and night games is even more confounding considering how the air is considered to be thinner during the day at AT&T Park, with the heavier moist air at night considered to be detrimental to hitters.
