Fils now leads the Green Group with two wins from two, while Dominic Stricker defeated Luca Nardi 4-1, 4-1, 4-2 in the same group for his first victory in Jeddah.

Fils is the only player in the draw ranked inside the Top 50 at the Next Gen Finals, as the tournament opened at its new home in Saudi Arabia on Tuesday.
