World number 14 Goffin was the only seed in action on a day taken up predominantly by qualifiers and swiftly stamped his authority on the match, winning five games on the spin to race into a 5-1 lead in the opening set.

Despite squandering three set points on Darcis' serve, Goffin cemented his lead in the eighth game, before again making a strong start to the second set.

Goffin had the match at his mercy after opening up a 4-0 advantage and wrapped up the win on his second match point to become the first man into the second round.
