Sinner doesn't miss a shot: Michelsen knocked out, Jannik flies to the quarterfinals in Miami

Jannik Sinner grits his teeth but reaches the quarter-finals at the Miami Open, defeating Alex Michelsen with a score of 7-5 7-6. For the Italian, this is the twentieth qualification for the quarter-finals in a Masters 1000, with his streak of consecutive sets won rising to 28.

The match proves to be more complicated than expected. Michelsen, a 21-year-old American, starts strong thanks to a solid serve and remarkable consistency in baseline rallies. In the early games, he concedes nothing, while Sinner stays close despite some unforced errors. The key moment comes in the ninth game, when the Italian earns three consecutive break points: the American saves them all and even saves a fourth opportunity, but at 5-5 he falters, allowing Sinner to close the first set.

In the second set, the balance increases and the difficulties in service games rise. Sinner loses serve for the first time in the tournament and Michelsen soars to 5-2, reaching the point of serving for the set. The Italian responds with character, recovers the break, and drags the match to a tie-break, where he secures the decisive minibreak at 4-4 and closes the match.

The day also sees the elimination of other Americans. The defeat of Sebastian Korda is surprising, as he is defeated in a comeback by the Spaniard Martin Landaluce (2-6, 7-6, 6-4), just days after his victory against Carlos Alcaraz. Taylor Fritz also exits, surpassed by the Czech Jiri Lehecka in three sets (6-4, 6-7, 6-2), while Arthur Fils prevails over Valentin Vacherot after a battle that ended 6-4, 6-7, 6-4.

In the women's tournament, victory for Karolina Muchova, who defeats 7-5 7-6 the Canadian Victoria Mboko. The tie-break of the second set is decisive, in which the young North American, after having come back, makes a fatal error handing the match to her more experienced opponent.
