Stefanos Tsitsipas got back to winning ways at the Open 13 on Wednesday with a comfortable 6-4 6-2 victory over Hubert Hurkacz.
The Australian Open semi-finalist had suffered defeat to Damir Dzumhur in his first match at last week's Rotterdam Open, the Greek having been given a first-round bye.
He suffered no hangover in Marseille, though, with a comprehensive victory over the world number 78, Tsitsipas only needing 59 minutes to secure his progression.

Shapovalov hit 18 aces and only lost eight of his first-service points but it was not enough as Kukushkin rounded out a 6-4 7-6 (7-4) win by converting his third match point.
Former champion Gilles Simon is also through, the 2015 winner bouncing back after losing the first set against Peter Gojowczyk to triumph 4-6 6-4 6-2.
In the final first-round matches there were wins for Matthias Bachinger, Gregoire Barrere and Ugo Humbert.
