Next Gen experiment leaves champ Tsitsipas 'confused'

MILAN - Stefanos Tsitsipas capped a roller-coaster season by winning the Next Gen ATP Finals on Saturday, but the rising Greek star conceded he was slightly bemused by the rules of the tournament.

The 20-year-old from Athens came through 2-4, 4-1, 4-3 (3), 4-3 (3) on his third match point against 19-year-old Australian Alex de Minaur after one hour and 41 minutes to win his second career title after Stockholm last month.

"To be honest with you, I'm confused myself. I don't really know what I liked and what I didn't like," admitted Tsitsipas.
