Angel Stadium has been the home of the Angels since their move from Los Angeles. In 1964, ground was broken for Anaheim Stadium and in 1966, the then-California Angels moved into their new home after having spent four seasons renting Dodger Stadium (referred to during Angels games as Chávez Ravine Stadium) from the Dodgers. The stadium was built on a parcel of about 160 acres (0.65 km2) of flat land originally used for agricultural purposes in the southeast portion of Anaheim. Consistent with many major-league sports stadiums built in the 1960s, it is located in a suburban area, though one that is host to major tourist attractions. The field dimensions (333 feet instead of 330, for example) were derived from a scientific study conducted by the Angels. Based on the air density at normal game times (1:30 pm and 8 pm), the Angels tried to formulate dimensions that were fairly balanced between pitcher, hitter and average weather conditions. The Angels tinkered with those dimensions several times, expanding or contracting parts of the outfield by a few feet here and there, to try to refine that balance. None of this seemed to matter to their Hall of Fame pitcher Nolan Ryan, who threw two of his record seven no-hitters in this ballpark, and racked up 2,416 of his 5,714 career strikeouts in eight seasons with the Angels (Ryan stats from The Sporting News Baseball Record Book). One of the no-hitters, on June 1, 1975, was his fourth, which tied Sandy Koufax's career record, one Ryan would eventually supplant.
