Venus Sets New Record, Hair Cuts On Court, Michelsen vs. Giron & More

Good morning, Court Theorists! ☕️

…or at least it was when I started writing this newsletter. Ever have one of those days where you knock over your coffee, walk out to a flat tire, and your work tech isn’t teching? That’s how today started here at Court Theory HQ.

But! Do you know what saved the day? Tennis. I decided to let the universe work itself out while I kept my plans to hit the court. Exercise + sunshine + a few laughs = a much better afternoon. And that’s why you’re getting The Daily Theory now.

Today’s tennis mood: Redemption + anticipation.

Let’s tennis!

🎾 Record setter: Venus Williams set another record on Tuesday. Williams, 45, played Tatjana Maria, 38, and their combined age of 84 years and one day made for the highest combined age in a main draw match in WTA history. Certainly, Venus would have liked to have been the winner while making history. Unfortunately, she wasn’t. Instead, she was the victim of a thousand Maria slices, losing 6-4, 6-3.

🎾 Coming soon!: That would be a new documentary series on Andre Agassi. Chris Smith, who has directed documentaries including Jim & Andy: The Great Beyond, Wham!, and Devo, is set to direct the series for Apple TV. It will be the streamer’s second tennis documentary series after Boom! Boom! about Boris Becker.

  • Noteworthy: Justin Gimelstob, who has placed himself in every Agassi endeavor for the last few years, will be an executive producer.

🎾 One to watch: Marcos Giron vs. Alex Michelsen (2nd round - ATP 250 - Auckland): Two American hard court players facing off? Yes, please. Each time these two play, it’s a battle. Expect heavy hitting off the ground from both, with each of them trying to spread the court for a short ball to come forward. This match will likely come down to how well they serve.

  • The record: Marcos Giron leads the head-to-head record over Alex Michelsen 2-0.

  • On the line: This match is about pride, bragging rights, and Australian Open prep.

(Yesterday’s poll results: 100% of you voted that Iva Jovic would defeat Janice Tjen. Indeed, she did! She won 6-0, 6-1. 😅)

And that’s game.
