Rafael Nadal has been forced to withdraw from his ATP Cup clash with Stefanos Tsitsipas. The Spaniard said 'not well enough' to play. Nadal is currently preparing for the Australian Open. But his involvement in that competition is now uncertain. "Hi all,” he said. “We have decided with Team Spain and my team, to not play today the first match of the ATP Cup here in Melbourne since I have a stiff low back. Hopefully, I'll be better for Thursday. We have a strong team, all the best to [Pablo Carreno-Busta], [Roberto Bautista-Agut] and [Marcel Granollers]."
