Prediction published on 12/17/25, 4:25 AM  by Lou Aguila | Modified on 12/17/25 at 7:29 PM in Tennis Picks

No.2 seed Justin Engel of Germany will take on Alexander Blockx of Belgium in a battle of two exciting young stars on the ATP Tour at the 2025 NextGen Finals on Wednesday.

Will the 18-year-old Egnel (+155 underdog) pull off some surprise against the fast-rising Blockx (-188)?

Current Form:

Engel will try to make a name for himself in his first-ever NextGen Final. The young German qualified for the tournament featuring talented players under 21 after compiling a 40-33 record this year. A five-time ITF titlist, Engel has accomplished a few milestones on the ATP Tour this season. The young German reached his first ATP Main Tour-level quarterfinals after upsetting Alex Michelsen in the second round of the 2025 BOSS Open. He also became the second youngest player in the German Davis Cup team after Boris Becker, after downing Japanese Rei Sakamoto in his debut match.

Blockx qualified for the NextGen finals with his second tour-level win against Francisco Passaro at the 2025 Moselle Open. Blockx has already won three ATP Challenger-level titles in his career, but winning the NextGen Final title will definitely accelerate his progress on the tour. Blockx has compiled 42-27 record in 2025.
