Why your team should sign up for the

2021 Grand Slam World Series of Baseball In Panama City Beach, Florida.

Oklahoma Mudcats

Mr. Thompson: On behalf of the players, coaches and families of the 14 year old Mudcats from Mustang, Oklahoma, I would like to thank you for a job well-done. We played in the tournament last week, and we were all very pleased with your tournament. This is our team's third location for a "World Series" type of tournament, and your product is clearly better than what the other sanctioning organizations have to offer. Personally, between both of my boys, this was my 6th different "World Series" venue, and I would rank you number one. We were appreciative of the cleanliness and excellent grooming and care provided to make the fields a nice place to play. We found your umpires to be very professional, personable and efficient. They weren't perfect, of course, but neither were we. In fact, I guarantee we blew more plays than they did! We are also grateful for the kindness and attention from your on site staff/directors. They were always friendly and helpful. Again, thank you for the job you do. I was really excited when I found your organization online and learned it freed us from the ridiculous constraints, fees and regulations imposed by the most prominent sanctioning organization in this part of the country. I will definitely be promoting your tournaments to the people in our area, as I am sure many are not aware of other options. Sincerely, Gerald A Amundsen II Oklahoma Mudcats
