It’s one of the oddest sights in any Major League ballpark. The left field wall at Oracle Park abruptly rises up a good 3 feet near the left field foul pole, carries 6 feet across, and then dips right back down to its normal height.
I’m referring to the curious outfield wall alteration that makes room for the left side of a Chevron ad depicting a cartoon dog standing in a cartoon car catching a baseball.
It’s the fourth iteration of the ad, which has been there in some form since the stadium opened in 2000. The ad requires approval from Major League Baseball because it quite literally changes the stadium’s “ground rules” — special rules particular to each MLB park that designate where fair and foul territories are.
