While historic Scottsdale Stadium I had many suitors in its time... Scottsdale Stadium II has always been the dedicated spring home to the San Francisco Giants, since it made its debut on March 12th 1992. Most Spring Training stadiums in Arizona are only open for 6 weeks out of the year, then they remain dormant until the following season. When Scottsdale Stadium II opened however, it would become the #1 most utilized ballpark in all of America (hosting more games than any Major or Minor League Baseball stadium).
