Lorenzo Sonego has scored the eighth ATP win in Sao Paulo, defeating Federico Delbonis 6-4, 6-4 in an hour and 23 minutes after a great display on serve. The Italian lost just 14 points on serve in ten games, never facing a break point and keeping the pressure on Delbonis who couldn't match those numbers, dropping serve twice from four opportunities he gave to Sonego.
The Argentinian wasted five game points at the start of the match and he suffered a break after netting an easy forehand to chase the result right from the start. Never challenged on serve, Lorenzo sealed the opener with a service winner in game ten and he moved ahead in the third game of set number two as well when his forehand down the line found the perfect target.
Delbonis was unable to make any damage on the return and Sonego blasted an ace in game ten to wrap up the win and move into the next round. Christian Garin needed 81 minutes to dismiss Pedro Sousa 7-6, 6-2, fending off four out of five break points and taking the rival's serve three times to seal the deal in straight sets.
Garin was 4-2 up in the opener before Sousa pulled the break back to level the score at 4-4, saving three break points in game 11 to set up a tie break where Christian won seven straight points for a 7-3. The Portuguese suffered breaks in games four and eight in set number two to propel Garin over the finish line and into the last 16.
Roberto Carballes Baena was a set down before overpowering Maximilian Marterer 3-6, 6-1, 6-2 in an hour and 50 minutes for his fifth win on South American clay this February. The German fired 11 aces but he lost the ground after the opening set, unable to defend his second serve to face 11 break points and get broken four times.
Serving at 72%, Roberto played well on both the first and second serve, playing against just three break points and losing serve once to dominate in sets two and three. Maximilian broke in the second game of the match and that was enough to earn the opener for him, saving a couple of break points and cementing the first set when Roberto sent a forehand long in game nine.
The Spaniard bounced back in set number two, breaking Maximilian at love in game two and once again at 4-1 before he grabbed the set with a service winner a few minutes later to set up a decider. There, he lost just four points on serve and controlled the scoreboard with two breaks in games one and seven, wrapping up the win with a hold at love in game eight to reach the last 16.
The 8th seed Taro Daniel won eight points more than Marco Trungelliti but he fell short in the end, losing 6-4, 3-6, 7-6 to send the Argentinian over the finish line. They traded breaks early in the deciding set and stayed neck and neck until the tie break that Trungelliti won 7-5 to secure the 11th ATP win in a career.
