The Giants have decided to install a new scoreboard for the 2019 season and you can see this tweet to get a glimpse of the process from late last week...
Top Golf at AT&T Park is a brilliant idea. Also, Giants are in the process of replacing their scoreboard. New one is going to be massive: pic.twitter.com/KBEm8g2VHx
