1970 season, is the only long-term major league ballpark where a no-hitter was never thrown during its existence. There are three recently built fields where no-hitters have not yet been thrown, Busch Stadium, Truist Park, and Target Field. Four parks presently in existence for a decade or more have only seen one no-hitter each: Coors Field, the hitter-friendly home of the Colorado Rockies (Hideo Nomo on September 17, 1996); the Orioles' current home, Oriole Park at Camden Yards, known for being hitter friendly (Nomo on April 4, 2001); PNC Park, the current home of the Pirates, which like Forbes Field is known for being hitter-friendly (Homer Bailey on September 28, 2012); and Petco Park, home of the San Diego Padres, which initially was known as a pitcher's park but was modified with shorter fences in 2013 (Tim Lincecum on July 13, 2013). American Family Field, home of the Milwaukee Brewers, has hosted two no-hitters, but only one involved its home team. Both no-hitters were thrown by the Chicago Cubs—Alec Mills threw a no-hitter on September 13, 2020, against the Brewers; and Carlos Zambrano pitched one on September 14, 2008, against the "home" Houston Astros in a game displaced by Hurricane Ike. Nippon Professional Baseball There have been 66 no-hitters in Nippon Professional Baseball history. As noted above, unlike Major League Baseball, the Japanese league does not count combined or not shutout no-hitters. Negro leagues Ongoing research by baseball historians has revealed the existence of 34 no-hitters thrown in Negro league baseball; the research has had to clarify differences between play from teams and barnstorming, and one of the no-hitters was done at a Benefit All-Star Game. In 2020, Major League Baseball announced the addition of the seven "Negro Major Leagues" that played from 1920 to 1948 as major leagues, which recognized statistics from over 3,400 players that played in those seasons, which will only increase the need for further research and verification over no-hitters. This presumes that 22 to 24 no-hitters from that said era (22 regular season, one postseason, one All-Star game) could be recognized by official record books such as Elias in future years. There are also six games that were prematurely cut from the intended length of nine innings that were called due to weather that ranged from 1926 to 1945, one of which includes Luther Farrell and his seven-inning no-hitter in Game 5 of the 1927
