Jannik Sinner unstoppable: overwhelmed Tiafoe, is in semifinals in Miami

There is no history between Jannik Sinner and Frances Tiafoe in the quarterfinals of the Miami Masters 1000. After his triumph in Indian Wells, the world and seeded number two extends his streak of consecutive victories to ten, leaving no way out for the American, number 19 in the seedings and 20 in the ATP rankings. The South Tyrolean star, in fact, smashes a clear 6-2 6-2 to the American after just one hour and eleven minutes of play.

Sinner starts off strong right away by taking the serve away from Tiafoe in the opening game: the Azzurro drags the American to the advantages and at the first useful opportunity hits back. Jannik confirms the break at zero with a pair of aces, then with two more goes up 3-1. The South Tyrolean in reply continues to put pressure on Tiafoe, who is forced to break serve for the second time in the set with a couple of errors.

Sinner, on the other hand, is relentless at the serve: aces abound (there are 8 at the end of the partial) and after half an hour the world number two makes the first set his (6-2), dominated far and wide. In the second set, Tiafoe risks losing serve again in the opening game but the American saves himself by winning two big exchanges. The resistance, however, was short-lived: in the third game Tiafoe cleared two more break points but with a double fault and a backhand free he surrendered.

Sinner confirmed the break with two more aces that by now were no longer news. The only relative moment of difficulty for the Blue on serve comes in the sixth game in which the U.S. manages to drag Jannik to the advantages but he gets out of trouble again with his serve. In the seventh game Sinner finds another break (to zero) before closing on the first match point with yet another ace (the fourteenth).

Thanks to this victory Sinner enters the semifinals at the Miami Open. There he will face the winner of the match between Alexander Zverev, world and seeded number three, and Francisco Cerundolo, seeded number 18 and world ranked 19.
