Alexander Zverev will compete in the Roland Garros third round for the seventh time in the previous eight years. The last year's semi-finalist returned to Court Philippe-Chatrier for the first time since that terrible ankle injury against Rafael Nadal.
Despite some strong feelings, Alexander played well and scored a 6-4, 6-2, 6-1 triumph over Alex Molcan in an hour and 58 minutes. Zverev played well behind the first and second serve and defended all eight break points, six in the encounter's closing stages.
Molcan failed to follow that pace, dropping half of the points in his games and allowing Zverev to grab six breaks from 16 opportunities. The German hit 42 winners and 28 unforced errors, kicking off the action with a break and never looking back.
Alexander had the upper hand in the shortest, mid-range and most extended rallies, passing the opening two rounds in Paris with no issues for the first time in a career.
