Stefanos Tsitsipas has revealed that he was left 'exhausted' after the Los Cabos Open earlier this month, but that his transition between the National Bank Canadian Open and the Cincinnati Open has been better.

World No. 4 Tsitsipas had a successful run at the Los Cabos Open in Mexico, defeating Alex de Minaur in the final of the ATP 250 tournament to take the title and move up in the Pepperstone ATP rankings.

However, the Greek player has since revealed that he found the transition to his next tournament at the Canadian Open in Toronto to be a difficult one as it threw off his sleep schedule. This was reflected by his results in Canada, as he went out in his opening round, losing to Gael Monfils who won the match 6-4, 6-3.

Speaking after his victory against Ben Shelton in the Round of 32 at the Cincinnati Open, Tsitsipas admitted that the late-night finishes at Los Cabos affected his play in Canada, but that his transition to Cincinnati was much better.

"It was difficult. I mean, that was my decision to go to Los Cabos, but it was difficult to transition, especially the tournament that I had to play after Los Cabos. The time difference made it very difficult for me to adjust in terms of my sleep. I had to play my match quite exhausted.

"But, yeah, the transition has been better after Toronto. I'm able to finally go to bed at normal times as opposed to Los Cabos where we would finish at 3:00 a.m. -- a.m., right? Yeah, a.m. Every day for a week, which is quite unusual for a tennis man," he said.

The 24-year-old also added that contrasting weather conditions were a factor in his difficulties at the National Bank Open, but accepted that it is just how the ATP Tour works sometimes.

"But this is our tour. This is how things work. I couldn't really acclimatize fast to these new conditions. The ball felt different in Toronto than it did in Los Cabos. Los Cabos, quite frankly, was a much more humid, hot place than Toronto where the ball felt much more lively there," he said.
