Switzerland’s Dominic Stricker moved to the top of the Red Group at the Next Gen ATP Finals on Wednesday with a victory over Italy’s Lorenzo Musetti that couldn’t have been any closer.

In the event’s unique format that features no-ad scoring and sets to four games, with tiebreakers at 3-3, Stricker prevailed 4-3 (5), 4-3 (6), 3-4 (7), 3-4 (6), 4-3 (3) at Milan, Italy.

The tournament includes the world’s top eight 21-and-under players, who were separated into two groups for round-robin play. The winner of each group will face the runner-up from the other group in the semifinals.

Stricker had a 20-9 edge in aces during the match that lasted 2 hours, 28 minutes. Stricker improved to 2-0, while Musetti fell to 1-1 in the Red Group round robin.

In the day’s other Green Group match, Great Britain’s Jack Draper beat Taiwan’s Chun-Hsin Tseng 1-4, 4-2, 4-3 (2), 4-2. Draper moved to 1-1, and Tseng slipped to 0-2.

The United States’ Brandon Nakashima is now 2-0 in the Green Group after a 4-1, 4-3 (2), 4-2 victory over the Czech Republic’s Jiri Lehecka. The result dropped Lehecka to 1-1, the same as Francesco Passaro, who won an all-Italian matchup against Matteo Arnaldi, 4-3 (7), 2-4, 3-4 (4), 4-3 (4), 4-3 (8).

Arnaldi, who slipped to 0-2, was unable to take advantage of three match points in the fifth-set tiebreaker before Passaro converted his third match point.
