18:05 CET - Game, set and match De Minaur. The Aussie cruised to the second set, advancing with a 7-5, 6-1 victory in the end.
Nadal will be disappointed with how faded as the match went on, but the fact that he was able to more than hold his own against one of the best in the world in his first tournament back will be encouraging for him.
17:20 CET - The first set is over and it's gone to De Minaur, who has won it 7-5 in just over an hour. Nadal had chances to go a break up himself but couldn't take them.
He's very much in this match though.
16:08 CET - Here we go then! Nadal and De Minaur are on court for the Spaniard's biggest clash in a long time. Will this be the start of his return to the top or confirmation that he may never get back there?

14:40 CET - Ons Jabeur (29) has finally won again! After losing six matches in a row, the world number nine has beaten Ekaterina Alexandrova (29) 2-6, 6-3, 7-6 in Stuttgart.
She needed that.

09:10 CET - The main event today is of course the clash in Barcelona between Rafael Nadal (37) and Alex de Minaur (25), which will give us our biggest indication yet as to whether the Spaniard will be able to compete for titles or just make up the numbers in the final stage of his career.
Speaking ahead of the match, Nadal said it would be stupid to consider him the favourite despite his imperious record on clay and at the tournament specifically.
