An engineer overthinks tennis in a daily journal.
Since I tangentially mentioned the Wilson Triniti tennis ball over the weekend, now seems like the perfect time to discuss this new innovative ball. As I started in on my coverage for today, I stumbled across a great mystery. What is the approval status of the ball?
Effective January 1, 2021, the Fair Oaks Tennis Center in Dallas is permanently closed. To the best of my knowledge, the only place where the closure notification has been published is on the Facebook page for the facility. The announcement of the impending shut down was first shared on December 6.
When reviewing posts from 2020, I had two realizations. First, I somehow still do not yet own a set of singles sticks. Second, I missed a subtle detail of the rule in my initial pass through that section. I wrote more than I would have anticipated about the singles sticks last year.
In the earliest days of this site, I posed the rhetorical question, “How do I not routinely carry a socket wrench in my bag to adjust net tension?” That quote came from “I just can’t handle the tension!” which was published on January 9, 2020 and discussed the rules around the proper tension for the net. At the time, I lamented that I had never seen a USTA umpire check the tension of the net prior to the match.
A short time after I wrote extensively about the ITF tennis ball testing procedures in 2020, I learned that both the USTA and Tennis Australia also have testing facilities and procedures for tennis ball testing. In fact, both of those national associations publish a list of approved balls that is divergent from the ITF list.
