When a game goes over the total at Petco Park is usually isn't by much and rarely do we see two teams combine for double-digit runs. But the last two contests – against the weak hitting San Francisco Giants – have each produced 11 runs. And on five occasions during those two games the ball managed to leave the playing field in fair territory. There is a theory among bettors that Petco Park plays a bit more realistic during stretches when the "marine layer" isn't as strong. According to
, this tends to happen during the day and later in the season. Just something to consider when playing Padres totals.
“In the simplest terms, when you’re close to the water, there’s more moisture in the air and the air is cooler,” said Miller. “The air becomes less dense with water in it, lighter than typical air molecules, so the ball can fly farther in the moister air. But when the marine layer moves in, like a big blob of cold air pouring over the stadium walls and onto the field, the air is more dense and harder for the ball to go through.
