👋 Welcome back to The Daily Theory, our morning rundown to help you stay on top of your favorite sport. I’m Allen McDuffee, your guide to all things tennis.

On tap today: Power’s out in Madrid, Andrey Rublev is a cautionary tale in a new era, Lorenzo Musetti is in a rematch against Stefanos Tsitsipas, plus more in tennis news today.

Let’s tennis!

Three Points

🎾 No power: If you turned on your favorite match from Madrid this morning only to realize it was nowhere to be found, that’s because there is a massive power outage affecting Spain and Portugal, affecting many parts of life in those countries, including transportation, emergency services, and payment processing. As for the tennis in Madrid, the ATP said the loss of power “is preventing the use of electronic line calling systems and also left a spider cam dangling over the court inside Manolo Santana Stadium.”

  • What she said: Coco Gauff was one of the few players to complete their match before the outage occurred. “No power where the showers are. So I’m about to take a shower and I’ll let you all know how it goes,” she posted on Instagram.

🎾 Rublow out: When the next rankings come out, Andrey Rublev will drop out of the top 10 and plummet nearly out of the top 20 after not only failing to defend his title in Madrid but also logging a 2-6 record in his last six events. It’s been a rough stretch for a number of top 10 mainstays who had one or two good tournaments last year. The consistency of other players in the top 20 means first-match exits (Rublev has had six so far this year) will cost you.

  • Next: Rublev only has 150 points to defend between Rome and Roland-Garros, and he has no points to defend in the grass season after not winning a match on that surface last year. So, there are opportunities to make up lost ground. But is his mind right to pull it off? Can Marat Safin get his mind right to gain that ground?

🎾 Check the mark: Alexander Zverev received a code violation on Sunday for grabbing his phone and taking a picture of a ball mark that was well wide of the line, but was called good by the electronic line-calling system. This is hardly the first case of a player disagreeing with an ELS call. And, to be clear, it’s not as if players always agree with humans, either. However, the Zverev case might be the most egregious discrepancy between the call and the mark left on the clay. This recent spate of problematic calls is raising serious questions about the readiness of the system on clay. No doubt Roland-Garros organizers are sitting smugly at their insistence that they will stick with human line judges.
