World No. 1 Rafael Nadal and in-form Daniil Medvedev have been drawn together in Group Andre Agassi for this year’s ATP World Tour Finals. The pair are joined by defending champion Alexander Zverev. Greek sensation Stefanos Tsitsipas is also in Group Andre Agassi.

Group Bjorn Borg will feature 20-time Grand Slam winner Roger Federer, Austrian Dominic Thiem, ATP Finals debutant Matteo Berrettini and Novak Djokovic.

Earlier today, Rafa’s PR manager Benito Barbadillo said:

MRI scan revealed he suffered a right abdominal strain.

He will travel to London to train, will start serving on Thursday or Friday, and hopes to be ready to play on Sunday or Monday.

Rafa posted on Twitter:

Hello everyone. Yesterday I had a resonance in Mallorca and despite having a small strain in the right abdominal rectum, I will travel to London.

Thursday or Friday I will start adapting to the surface. The idea is to be able to play the ATP Finals in London. Thanks for the support!

Our champ has withdrawn from the finals on four occasions since it moved to London in 2009, while he pulled out after just one match in 2017 following defeat to David Goffin.
