Jo-Wilfried Tsonga and Marin Cilic made it to the fourth round of Miami Masters in straight sets, whilst Sam Querrey progressed after Raonic had retired.
20th-seeded John Isner blasted twenty aces past seed number nine Cilic, yet that was not enough to eliminate his third round opponent. Despite hitting only a couple of aces, the Croat still had a better first serve point won ratio, not to mention his dominance in winning second serve rallies (65%-35%). Service games were short, including the ones that ended in a break. The US player acquired one straight away, but let Cilic turn the set around and get into the driver’s set by 4-2. The Croat held his remaining two serves to love and went one nil up. There were no losses of serve in the following set, so it was up to the tie-break to separate the players. Nine-time ATP title holder Cilic eventually generated a triple match ball and did not hesitate to seal his 6-3, 7-6 (3) victory.
Sixth-seeded Frenchman Tsonga was a dominant figure in the clash against World No. 49 Jarkko Nieminen of Finland. He needed to fend off two break balls by 2-2 in the opener, but he raised the level of his game as the set progressed and seized a couple of unseeded Nieminen’s serves to go one nil up. The Finn’s back was against the wall by 4-2 in the second set and there was no way he could avoid a third round exit. Tsonga was soon serving to secure his spot in the last 16 at Sonny Open Tennis and he tucked away the match ball number one to achieve a 6-3, 6-3 smooth triumph. The Frenchman won 71% of 2nd serve points as well as 69% of 2nd return points, thus exceeding his opponent by 40 percents in each of the categories. He will take on Cilic in next round.
Seed number 20 Querrey was given a walkover as Canadian Milos Raonic, seed 14, pulled out of the tournament due to illness. The American will confront Berdych in the last 16.
