Roberto Bautista Agut insists he doesn’t want Rafael Nadal to be injured despite wanting to be able to play at the ATP Finals.
Doubts remain over whether Nadal will be able to play at the season-ending event after he suffered a right abdominal strain at the Paris Masters on Saturday.
Nadal is expected to work on his serve at practise on Thursday which will provide a better indication of whether he is able to play.
Should Nadal pull out, Bautista Agut is first in line to replace him.
However, Bautista Agut says participating in the event at the expense of Nadal is not something he is wishing.
He told Spanish publication Marca: “I would like to be able to play.
“But on the other hand, I don’t want anyone to be injured, let alone Rafa.”
Bautista Agut has had a strong year, winning the Qatar Open in January after beating Novak Djokovic in the semi-finals.
He also reached the semi-finals of a Grand Slam for the first time when he made it through to the last four at Wimbledon and this week moved to a career-high of ninth in the world rankings.
Nadal is set to make a decision on his fitness on the weekend.
Nadal has been drawn in the same group as Alexander Zverev, Stefanos Tsitsipas and Daniil Medvedev.
And Bautista Agut backed his fellow Spaniard to come through the group if fit.
He said: “It is tough, because they are the eight best in the world.
“It will depend more on Rafa than on the rivals, since if he is well and plays at a high level, it doesn’t matter who is ahead.”
The ATP Finals get underway on November 10
