			The Italian 20-year-old, seeded 11th, took a long time to settle 
			down with 19 unforced errors in the first set and the Spanish 
			claycourt specialist quickly ran away with it.
 
 Sinner upped his game to break his opponent, ranked 89th in the 
			world, and move 5-4 up in the second but had to battle from 0-40 to 
			hold serve and level the match.
 
 Another break midway through the third set gave him a two-game 
			cushion and Sinner bagged the set when his opponent sank a forehand 
			into the net.
 
 In a fierce baseline battle lasting almost four hours, the pair 
			traded early breaks in the fourth set but Sinner got another to go 
			4-2 up.
 
 Carballes Baena, who reached the third round in Paris two years ago 
			with five-set five-hour win over Denis Shapovalov, finally 
			surrendered when he sent a backhand long on the Italian's first 
			match point.
