If the link goes to the club’s home page, but you have a problem such as outdated information, etc., please write to the club itself. Most clubs place a contact link somewhere on their page, or you can try an address like webmaster@(the domain name of the club, without the www -- www.ballclub.com becomes just ballclub.com).
NOTE: I have nothing to do with any team whose ballpark I feature on this site. I cannot help you with ticketing, special events, lost-and-found, etc. Please contact the club directly, using the Web link on my Index of All Pro Parks, by League.
