Built in 2019, Estadio Alfredo Harp Helu plays host to the Diablos Del Mexico in the Mexican League. The inaugural game in March of that year was an exhibition between the Diablos and San Diego Padres. It ended 11-2 (with just one home run) and is the only game in that venue that has featured an MLB team.
If it were a Major League stadium, Harp Helu would no doubt be the most run producing venue in the league. It sits 7,349 feet above sea level (2,200 above Coors Field) with relatively small dimensions. The outfield is actually not small, but it plays as such given the ball flies 7-8% farther than the MLB standard. The wall is labeled 400 feet to center and 332 in the corners (actually 325 to the foul poles). These measurements alone are close to MLB average, but the outfield is larger than the typical park since it's shaped like a circle.
Estadio Alfredo Harp Helu will host MLB's Mexico City Series between the Giants and Padres April 29-30.
