What follows is our annual review of the general influences of park factors, an overview of different types of venues, and a breakdown of Kauffman Stadium, Tropicana Field and Sutter Health Park. Vincent Carchietta-Imagn ImagesThe primary park factors are runs, hits and home runs. Petco Park (San Diego Padres) is correctly known as a pitcher's park, but it also favors homers, which may be a surprise. PNC Park (Pittsburgh Pirates), Chase Field (Arizona Diamondbacks) and Oracle Park (San Francisco Giants) are all homer-suppressing parks that play neutral for runs. The new dimensions will no doubt yield more home runs, especially to the pull side, since center field remains deep.
