Jack Sock has a theory for why some may not perform well at the Miami Open after Indian Wells.
The two Masters 1000 events take place one week after the other in what is known by fans as the ‘Sunshine Double’.
The tournaments in question are two of the most popular on the tennis circuit, as fans flock through the gates to catch the pulsating action.
But one of the biggest challenges for ATP and WTA Tour players is competing in both events where the conditions are significantly different from each other, which can take some time to adjust to.

Jack Sock thinks more players care about playing at Indian Wells than Miami
Indian Wells is played in the hot and blustery conditions in California, on one of the slowest courts on the ATP Tour.
In Miami, there is the humidity factor, and the courts are much faster than in Indian Wells, despite the new surface that was played for the 2025 event.
Furthermore, there is a very short turnaround, as the Miami Open commenced just three days after the Indian Wells finals.
This topic was discussed on the Nothing Major podcast, and former World number eight Jack Sock shared his view.
“I think it is a combo of that. I think it almost proves our Indian Wells vs Miami debate. I think players just care more about Indian Wells,” Sock said.
“The travel going across the country, especially if you are playing late at Indian Wells, you are getting to Miami later than you usually would if it was a fresh week.
“And I think as we all know it can be crazy humid, it can be disgusting conditions out there weather wise and coming from very dry and way easier to play out in the desert than out there, especially for a crazy sweater like me.
“I did not look forward to going to Miami because I knew I would struggle in the heat. It is probably a combo of everything plus it’s a way different feel and way different event.”

Players have struggled to replicate Indian Wells performances in Miami
It is difficult for players to make the transition from the Indian Wells Masters to playing at the Miami just days later, especially if they make a deep run in California.
This has been the case in 2025, and as both Indian Wells champions Jack Draper and Mirra Andreeva have already exited the Miami Open.
Runner-up Holger Rune, as well as the semi-finalists Carlos Alcaraz and Daniil Medvedev, both lost their opening matches in Miami.
Indian Wells semi-finalist Madison Keys is also out of the Miami Open, after suffering defeat to 19-year-old Alexandra Eala.
The change in conditions and short turnaround seems to have affected these players, and they will need to regroup before the tour switches to the clay.
