AT&T Park, San Francisco
A picturesque open-air ballpark in San Francisco's trendy Mission Bay area of China Basin, AT&T Park (née Pac Bell Park, née SBC Park) is one of the design jewels of architects HOK Sport. Wedged into an asymmetrical shape by the imposition of San Francisco Bay and facing almost due east, the park's right field line is only 309 feet, fully 30 feet shorter than the left field corner. A steep angle, however, makes the right field power alley deeper than the left (421 vs 404), and the sharp angles make the 400 feet to dead center closer to home plate than the alleys. A Willy Mays high wall (24 feet) in right field helps balance the short porch, so balls aimed at McCovey Cove have to first get over that wall. That right field wall itself contains many arches and odd angles, as well which have caused enough bad bounces to earn it the nickname 'Triples Alley.' Despite all the quirks, AT&T Park plays as a neutral park, overall, with summer days favoring hitters, oddly, and the damp nighttime air being particularly helpful to pitchers. As an open-air park by the Bay, the park is also quite subject to variable winds.
