The youngest player in the draw and the home favorite Jannik Sinner is the first player to book the place in the semi-final at the Next Gen Finals in Milan, storming over Mikael Ymer 4-0, 4-2, 4-1 in quick 56 minutes. It was another thrilling performance from an 18-year-old, dropping 12 points in service games and fending off all five break chances to mount the pressure on the Swede who couldn't endure it, losing more than half of the points in his games and getting broken four times to propel Jannik into the last eight.
The Italian hit 16 winners and 23 unforced errors, reducing his opponent to just four winners and 18 mistakes and controlling the scoreboard all the time to keep the perfect score on his Next Gen Finals debut, having the upper hand in both the shortest and mid-range exchanges.
Jannik held at love in the first game and forced an error from Mikael in game two for an early break and the momentum on his side. Another hold at love pushed Sinner 3-0 up before he wrapped up the opener with the second break in game four for a 4-0 lead after only 12 minutes.
The Swede had his chances in set number two, earning a couple of break chances in the third game that Jannik defended with winners, erasing another break point at 2-2 and securing the set with a break in game six for a massive lead and another big step towards the victory after less than 40 minutes.
Facing two break opportunities in the first game of the third set, Sinner landed two winners to repel them, seizing a break in the next game following a terrible forehand from Ymer and moving over the top with a hold in game five to secure the place in the last four.
In the first match of Group B, the 2nd seed Frances Tiafoe toppled the 3rd seed Ugo Humbert 4-2, 4-3, 3-4, 4-1 in an hour and 42 minutes to stay in the semi-final chase. Both players had more winners than unforced errors and it was Humbert who delivered higher numbers, staying aggressive but missing the opportunity for a more favorable result after squandering all three break chances and giving serve away three times to push Frances towards the victory.
The American lost the third set in the tie break, bouncing back immediately and scoring breaks in games three and five in set number four to cross the finish line, hoping for more of the same against Ymer on Thursday.
