From the USTA Adult National Tournament FACEBOOK Page:
Unfortunately, we were not able to find a replacing host venue for the Men’s 55 and 80s Grass Court National Championships.
After contacting many different venues and exploring various options, we are forced to cancel these events for 2019.
These events will be back in the calendar for 2020 with a new hosting venue, and we are looking forward to supporting these National Championships.
Thank you for your understanding and let me know if you have any questions
