Research by the Elias Sports Bureau, baseball’s official statistician, indicated that previously the best performance by home teams had been 12-0 on May 23, 1914. That included four games that day in the Federal League, then considered one of three major leagues.

Cleveland and Miami also needed extra innings to prevail in their ballparks. Other winners were the Gi- ants, Toronto, Tampa Bay, Kansas City, Minnesota, St. Louis, Arizona, San Diego, the New York Mets, the Chicago Cubs, the Chicago White Sox and the Los Angeles Dodgers.
